The part represented by

One of the lines that is x+y=1 meets the axes (0,1) and (1,0) respectively. Then the lines are joined to obtain the line that is x+y=1. Therefore, it is clear that (0,0) the equation satisfies

The region that is represented by is first quadrant, and further satisfies these inequations. The graphic plotting is given below:

The shaded region OBC shows the feasible region is bounded, so, maximum value will occur at a corner point of the feasible region.

Corner Points are

When we substitute the values in Z, we get the following answer

Hence, the maximum value of Z is 4 at the point (0,1).

Question:3

Now let us convert the given inequalities into equation

We obtain the following equation

The region represented by xâ‰¤3:

The region represented by

The line 2x-3y+6=0 collides with the other axes to coordinate (-3,0) and (0,2) respectively. Then the lines are joined further to obtain the line 2x-3y+6=0. So, the part that contains the origin then represents the other solution set of the inequation

Looking at the graph we get,

The shaded region OBCD is the feasible region is bounded, so, minimum value will occur at a corner point of the feasible region.

Corner Points are O(0,0), B(0,2), C(3,4) and D(7,0)

Now we will substitute these values in Z at each of these corner points, we get

The region represented by

The line that has 2x +y=104 then meets the other coordinate axes (52,0) and (0,104) simultaneously. Then we need to join the points to get the result of 2x +y=104. The origin then represents the solution set further of the inequation

The first quadrant of the region represented is

The graph of the equation is given below:

The shaded region ODBA is the feasible region is bounded, so, maximum value will occur at a corner point of the feasible region.

Corner Points are O(0,0), D(0,38), B(44,16) and A(52,0)

Now we will substitute these values in Z at each of these corner points, we get

The region represented by x + y â‰¤ 5:

The line that shows , then meets the axes that coordinate (5,0) and (0,5) respectively. We need to join the points in order to obtain the line . Hence, it is clarified that (0,0) then satisfies the inequation . Therefore, the region that has the origin represents the solution set of .

The region that is represented by

The line that is meets the coordinate axes (9,0) and (0,3) respectively to get the final answer. When we join the points we get the line . Therefore, it is then clear that the region doesnâ€™t contain the origin and represents the solution set of the inequation.

The graph is further given below:

The shaded region BEC is the feasible region is bounded, so, minimum value will occur at a corner point of the feasible region.

Corner Points are B(0,3), E(0,5) and C(3,2)

Now we will substitute these values in Z at each of these corner points, we get

The region that represents the first quadrant is

The graph for the same is given below:

The shaded region BEC is the feasible region is bounded, so, minimum value will occur at a corner point of the feasible region.

Corner Points are B(0,3), E(0,5) and C(3,2)

Now we will substitute these values in Z at each of these corner points, we get

The region representing

The line that is meets the other coordinate axes (4,0) and (0,2) respectively. Once we join these points we get the result . After joining the lines, it is then clarified that it does not satisfy the inequation . So, then the region that does not contain the origin then represents the set of solutions.

The region that is represented by

The other line that is meets the coordinate axes (3,0) and (0,3) respectively. When we join these points we obtain the line . It is then cleared that it does not satisfy the inequation. Therefore, the region that does not contain the origin further represents the solution set.

Region represented by is first quadrant, since every point in the first quadrant satisfies these inequations

The graph of these equations is given.

The shaded region ABC is the feasible region is bounded, so, minimum value will occur at a corner point of the feasible region.

Corner Points are A(0,3), B(2,1), and C(4,0) .

When we see the region, we can see that it is unbounded, and 3 is not the minimum value of Z.

When we decide this issue, we can graph the inequality 4x + y < 3 and then further check that whether the resulting does has the open half no point in common, otherwise Z has no minimum value.

The graph that is shown above, we can see that it is clear that there is no point in common with the region and therefore, Z has a minimum value of 3 at (0, 3).

Henceforth, the minimum value of Z is 3 at the point (0, 3).

[this is resistor constraint]

When we divide it throughout by 10, we get:

Looking at the table, we can see that the cost becomes Z=400x+200y.

Now when we minimize the cost, i.e. minimize

The subject to constraints are:

When we divide it by 40, we get:

Now will divide throughout by 200, we get

Also given the number of large vans cannot exceed the number of small vans

And [non-negative constraint]

So, minimize cost we have to minimize subject to

The constraints so obtained, i.e., subject to the constraints,

[time constraints for threading machine]

Now will divide throughout by 2, we get

And [time constraints for slotting machine]

And [non-negative constraint]

So, to maximize profit we have to maximize subject to

If we have to maximize the profit, then maximize

The constraints so obtained, i.e., subject to the constraints,

The company spends at most Rs 72000 a day.

Divide throughout by 120, we get

Also, company can make at most 300 sweaters.:

Also, the number of sweaters of type B cannot exceed the number of sweaters of type A by more than 100

.....(iii)

And [non-negative constraint]

So, to maximize profit we have to maximize subject to

Question:15

If we see the man rides his motorcycle for a distance of X km at a speed of 50km/hr then he will have to spend Rs.2 per km for petrol.

If we assume that the man rides his motorcycle for a distance of Y km at a speed of 80km/hr, then he will need to spend Rs.3 per km on petrol.

Assuming that he has to spend Rs.120 on petrol for a total distance so the constraint becomes,

Now also given he has at most one hour's time for total distance to be covered, so the constraint becomes

Now taking the LCM as 400, we get

..........(ii)

And [non-negative constraint]

He want to find out the maximum distance travelled, here total distance,

Now, we have to maximize the distance, i.e., maximize

Question:16

Answer:

If we refer to Exercise 11, we get the following information.

The manufacturer produces X units of type A circuits and y units of type B circuits. We make the following table from the given data:

Looking at the table, we can see that profit becomes .

When we maximize the profit, i.e. maximize .

If we see at the constraints that we have obtained, then the subject to constraints,

[this is resistor constraint]

Dividing it throughout by 10, we get the answer as:

And [this is transistor constraint]

Dividing it by 10 throughout we get

And [this is capacitor constraint]

Then divide it by 10, we get

And [non-negative constraint]

So, when we look at the maximize profit it is , subject to

When we convert it to equation, we get the following equation

The region that is represented by :

When the line meets the coordinate axes (10,0) and (0,20) respectively. Once after the lines are joined, we obtain the line . It is clear that (0,0) satisfies the inequation . So the region then represents the set of solutions.

The region represented by :

Once the line meets the coordinate axes (12,0) and (0,6) respectively, then the points are joined to get the final result that is . It is then clear that it satisfies the inequation and the region does not contain the origin.

The region represented by

The line then meets the coordinate axes (15,0) and (0,5) respectively. Once we join these points we obtain the line . It is clear that (0,0) satisfies the inequation x+3yâ‰¤ 15. So the region that contains the origin represents the solution set of the inequation .

Region represented by xâ‰¥0 and yâ‰¥0 is first quadrant, since every point in the first quadrant satisfies these inequations

The graph of the same is given below:

The shaded region OABCD is the feasible region is bounded, so, maximum value will occur at a corner point of the feasible region.

Corner Points are O(0,0), A(0,5) , B(6,3), C(9.3,1.3) and D(10,0)

Now we will substitute these values in Z at each of these corner points, we get

So from the above table the maximum value of Z is at point (9.3,1.3), but as the manufacturer is required to produce two type of circuits, so the parts of resistors, transistors and capacitors cannot be decimals. So we will consider the next maximum number.

Hence, the maximum value of Z is 480 at the point (6,3) i.e., the manufacturer should produce 6 circuits of type A and 3 circuits of type B so as to maximize his profit.

Question:17

Refer to Exercise 12. What will be the minimum cost?

Answer:

We get the following information referring to the exercise 12:

Let us consider that the firm has X number of large vans and Y number of small vans . We have made the following table:

According to the table, the cost becomes .

When we have to minimize the cost, i.e., minimize .

The subject to the constraints are as follows:

Then divide it by 40, we get

Then divide it by 200, we get

The number of the vans that are large exceed the number of small vans

So, when we minimize cost we have to minimize, Z=400x+200y, subject to

When we convert the inequalities into equation, we get the following equation

We can see the region represented by :

The line that is when it meets the coordinate axes (6,0) and (0,15) respectively we get the desired answer. We will then join these points to obtain the line 5x+2y=30. It is clear that (0,0) does not satisfy the inequation . So the region that does not contain the origin represents the solution set of the inequation .

The region that represents :

We can see that the line meets the coordinate axes (7.5,0) and (0,15) respectively. We will have to join these points to obtain the line . It is clear that (0,0) satisfies the inequation . So the region that contains the origin represents the solution set of the inequation .

The region represented by xâ‰¤y:

Then when the line x=y is a line that passes through the origin and doesnâ€™t touch any coordinate axes at any other point except (0,0). When we join the points we get line x=y.

Region represented by xâ‰¥0 and yâ‰¥0 is first quadrant, since every point in the first quadrant satisfies these inequations

The shaded region ABC represents the feasible region is bounded, and minimum value will occur at a corner point of the feasible region.

Now we will substitute these values in Z at each of these corner points, we get

So from the above table the minimum value of Z is at point

Hence, the minimum cost of the firm is Rs. 2571.43

Question:18

Answer:

Refer to the Exercise 13, we get the following data:

Let us assume that the company manufactures x boxes of type A screws and y boxes of type B screws. We make the following table from the given data:

Type A screws (x boxes) | Type B screws (y boxes) | Max time available on each machine in a week | |

Time required for screws on threading machine | 2 | 8 | 60 hrs = 60*60min = 3600min |

Time required for screws on slotting machine | 3 | 3 | 60 hrs = 60*60min = 3600min |

Profit | Rs 100 | Rs170 |

When we look at the table, the profit becomes, Z=100x+170y

Thus according to the table, the profit becomes, Z=100x+170y

The constraints that we have obtained that is subject to constraints:

[time constraints for threading machine]

Divide it throughout by 2, we get

And [time constraints for slotting machine]

â€¦â€¦â€¦â€¦..(ii)

And xâ‰¥0, yâ‰¥0 [non-negative constraint]

So, to maximize profit we have to maximize, Z=100x+170y, subject to

Now let us convert the given inequalities into equation.

We obtain the following equation

The region that represents x+4yâ‰¤ 1800:

We can say that the line meets the coordinate axes (1800,0) and (0,450) respectively. When we join these points, we get the desired line that is . We can say that it is clear that it satisfies the inequation and therefore the region that contains the origin further represents the set of solutions of the inequation.

The region represented by :

The line further meets the axes (1200,0) and (0,1800) respectively. After joining these points, we get the result that is . It is then clear that it satisfies the inequation . So the region that contains the origin represents the solution set of the inequation .

The graph is given below:

The shaded region OBCD is the feasible region is bounded, so, maximum value will occur at a corner point of the feasible region.

Corner Points are O(0,0), B(0,450), C(1080,180) and D(1200,0)

Now we will substitute these values in Z at each of these corner points, we get

So from the above table the maximum value of Z is at point (1080,180) .

Therefore, the final answer is maximum profit to the manufacturer is Rs.

1,38,600

Question:19

Answer:

When we refer to the exercise, we get the following information:

Letâ€™s take an assumption that the company manufactures x number of type A sweaters and y number of type B. We have made a table for your understanding which is given below:

Thus according to the table, the profit becomes, Z=200x+120y

If we have to maximize the profit, i.e., maximize Z=200x+120y

The subject to constraints is:

The company spends at most Rs 72000 a day

.

Divide throughout by 120, we get

Also, company can make at most 300 sweaters.:

Also, the number of sweaters of type $B$ cannot exceed the number of sweaters of type A by more than 100

i.e.,

And [non-negative constraint]

So, when we convert the inequalities into the equation we get the following answer:

We can say that the line 3x+y=600 meets the coordinate axes (200,0) and (0,600) respectively. Once the points are joined, we get the answer that is 3x+y=600. It is justified that 3x+yâ‰¤ 600. So the region that contain the origin represents the solution set of the inequation 3x+yâ‰¤ 600

The region represented by x+yâ‰¤ 300:

The line when it meets the coordinate axes respectively that is y= 100+x meets (-100,0) and (0,100) respectively and when the lines are joined we get the line y= 100+x. Then it is clarified that it satisfies the inequation. Therefore, the region contains the origin that represents the solution of sets of inequation.

The graph of the same is given:

The shaded region OBCDE is the feasible region is bounded, so, minimum value will occur at a corner point of the feasible region.

Corner Points are O(0,0), B(0,100), C(100,200) , D(150,150) and E(200,0)

Now we will substitute these values in Z at each of these corner points, we get

Hence, the final answer is the maximum profit to the manufacturer is Rs. 48,000, for making 150 sweaters each of type A and type B.

Question:20

Refer to Exercise 15. Determine the maximum distance that the man can travel.

Answer:

When we refer to the Exercise, we get the following information:

If the man rides his motorcycle for a distance of x km at a speed of 50km/hr then he has to spend Rs. 2/km on petrol.

And if he rides his motorcycle for a distance of y km at a speed of 80 km/hr then he has to spend Rs. 3/km on petrol.

He has Rs.120 to spend on petrol for covering the total distance so the constraint becomes

2x+3yâ‰¤120â€¦â€¦â€¦â€¦(i)

Given that he has only one hourâ€™s time to cover the total distance, then the constraint becomes

{as distance speed x time}

Now taking the LCM as 400, we get

And [non-negative constraint]

He want to find out the maximum distance travelled, here total distance,

Now, we have to maximize the distance, i.e., maximize

So, to maximize distance we have to maximize, ,$ subject to

When we convert it into equation we get

The region that is represented by 2x+3yâ‰¤120:

The line that is 2x+3y=120 further meets the coordinate axes (60,0) and (0,40) respectively and then when we will join these points we obtain the line 2x+3y=120. It is clear that (0,0) justifies the inequation 2x+3yâ‰¤120. So the region that contain the origin represents the solution set of the inequation 2x+3yâ‰¤120

The region represented by 8x+5yâ‰¤400:

We can see that the line 8x+5y=400 meets the coordinate axes (50,0) and (0,80) respectively. When we join these points we obtain the line 8x+5y=400. Therefore, it is clear that (0,0) satisfies the inequation 8x+5yâ‰¤400. So the region that contain the origin represents the solution set of the inequation 8x+5yâ‰¤400

The first quadrant of the region represented is xâ‰¥0 and yâ‰¥0. The graph is as follows:

The shaded region OBCD is the feasible region is bounded, and maximum value will occur at a corner point of the feasible region.

Corner Points are

When we substitute the values in Z, we get the following answer:

So from the above table the maximum value of Z is at point

Hence, the maximum distance the man can travel is or 54.3 km

The graph for the same is given below and also the final answer:

Question:22

Answer:

Let us say that the number of bikes per week of model X and Y are x and y respectively.

Assuming that model X takes 6 man-hours.

So, time taken by x bikes of model X = 6x hours.

Assuming that model Y takes 10 man-hours.

So, time taken by y bikes of model X = 10y hours.

So, the total man-hour that is available per week = 450

So, 6x + 10y â‰¤ 450

3x + 5y â‰¤ 225

The handling and the marketing cost of model X and Y is Rs 2000 and Rs 1000 per unit respectively.

So, total handling and marketing cost of x units of model X and y units of model y is 2000x + 1000y

The maximum amount that is available for handling and marketing per week is Rs 80000.

So,

Profits per unit for Models X and Y are Rs 1000 and Rs 500, Respectively.

Let total profit = Z

So,

Also, as units will be positive numbers so x, y â‰¥ 0

So, we have,

With constraints,

In order to maximize Z, that is subject to constraints.

We need to convert it into equation:

The graph for the same is given below:

ABCD being the feasible region.

The Value of Z as well as the final answer is given below.

The Value of Z at corner points A,B,C and D :

So, value of Z is maximum on-line BC, the maximum value is 40000 . So manufacturer must produce 25 number of models X and 30 number of model Y.

Question:23

The person needs at least 18 milligrams of iron, 21 milligrams of calcium and 16 milligrams of vitamins. The price of each tablet of X and Y is Rs 2 and Re 1 respectively. How many tablets of each should the person take in order to satisfy the above requirement at the minimum cost?

Answer:

Let us say that the number of tablet X be x and the number of tablet Y be y.

Iron content in X and Y tablets is 6 mg and 2 mg respectively.

Total iron content from x and y tablets = 6x + 2y

Minimum of 18 mg of iron is required. So, we have

Similarly, calcium content in X and Y tablets is 3 mg each respectively.

So, total calcium content from x and y tablets = 3x + 3y

Minimum of 21 mg of calcium is required. So, we have

Also, vitamin content in X and Y tablet is 2 mg and 4 mg respectively.

So, total vitamin content from x and y tablets = 2x + 4y

Minimum of 16 mg of vitamin is required. So, we have

Also, as number of tablets should be non-negative so, we have,

x, y â‰¥ 0

Cost of each tablet of X and Y is Rs 2 and Re 1 respectively.

Let total cost = Z

So, Z = 2x + y

Finally, we have,

Constraints,

We need to minimize Z, subject to the given constraints.

Now let us convert the given inequalities into equation.

We obtain the following equation

The region that is representing 3x + y â‰¥ 9 is the line 3x + y = 9 meets the coordinate axes (3,0) and (0,9) respectively. Once the points are joined, the lines are obtained 3x + y = 9. It does not satisfy the inequation and so the region that contains the origin then represents the solution set of the inequation 3x + y â‰¥ 9.

The region that is representing x + y â‰¥ 7 is the line x + y = 7 meets the coordinate axes (7,0) and (0,7) respectively. Once the points are joined, the lines are obtained v It does not satisfy the inequation and so the region that contains the origin then represents the solution set of the inequation x + y â‰¥ 7.

The region representing x + 2y â‰¥ 8 is the line x + 2y = 8 meets the coordinate axes (8,0) and (0,4) respectively. We will join these points to obtain the line x + 2y = 8. It is clear that (0,0) does not satisfy the inequation x + 2y â‰¥ 8. So, the region not containing the origin represents the solution set of the inequation x + 2y â‰¥ 8.

The regions that represent xâ‰¥0 and yâ‰¥0 is first quadrant, since every point in the first quadrant satisfies these inequations.

Given below is the graph:

Clearly, intersects feasible region only at B.

So, does not have any point inside feasible region.

So, value of Z is minimum at B(1,6), the minimum value is 8 .

So, number of tablets that should be taken of type X and Y is 1,6 Respectively.

Question:24

Answer:

Taking into consideration that Let number of days for which factory I operate be x and number of days for which factory II operates be y.

Number of calculators made by factory I and II of model A are 50 and 40 respectively.

Minimum number of calculators of model A required = 6400

So, 50x + 40y â‰¥ 6400

â‡’ 5x + 4y â‰¥ 640

Number of calculators made by factory I and II of model B are 50 and 20 respectively.

Minimum number of calculators of model B required = 4000

So, 50x + 20y â‰¥ 4000

â‡’ 5x + 2y â‰¥ 400

Number of calculators made by factory I and II of model C are 30 and 40 respectively.

Minimum number of calculators of model C requires = 4800

So,

Operating costs is Rs 12000 and Rs 15000 each day to operate factory I and II respectively.

Let Z be total operating cost so we have Z = 12000x + 15000y

Also, number of days are non-negative so, x, y â‰¥ 0

So, we have,

Constraints,

We need to minimize Z, subject to the given constraints.

Now let us convert the given inequalities into equation.

We obtain the following equation

The region that represents the 5x + 4y â‰¥ 640.

The line 5x + 4y = 640 meets the coordinate axes (128,0) and (0,160) respectively to get the final outcome. When we join these points to obtain the line 5x + 4y = 640. It is then clear that (0,0) does not satisfy the inequation 5x + 4y â‰¥ 640. So, the region not containing the origin represents the solution set of the inequation 5x + 4y â‰¥ 640.

The region that represents the 5x + 2y â‰¥ 400:

The line 5x + 2y = 400 meets the coordinate axes (80,0) and (0,200) respectively. We will join these points to obtain the line 5x + 2y = 400. It is justified that (0,0) does not satisfy the inequation 5x + 2y â‰¥ 400. So, the region not containing the origin represents the solution set of the inequation 5x + 2y â‰¥ 400.

The region represented by 3x + 4y â‰¥ 480:

The line that 3x + 4y = 480 when meets the coordinate axes (160,0) and (0,120) respectively. We will then try and join these points to obtain the line 3x + 4y = 480. It is clear that (0,0) does not justify the inequation 3x + 4y â‰¥ 480. So, the region not containing the origin represents the solution set of the inequation 3x + 4y â‰¥ 480.

The graph is:

The region towards the right of ABCD is the feasible region. It is unbounded in this case.

The value of Z at the corner points, is

Now, we plot to check if resulting open half has any point common with feasible region.

The region represented by

The line meets the coordinate axes (155,0) and (0,124) respectively. We will join these points to obtain the line $. It is clear that (0,0) satisfies the inequation . So, the region containing the origin represents the solution set of the inequation .

Clearly, intersects feasible region only at C

So, value of Z is minimum at C(80,60), the minimum value is 1860000 .

So, number of days factory 1 is required to operate is 80 and number of days factory 2 should operate is 60 to minimize the cost.

Question:25

We have constraints,

We need to maximize and minimize Z, subject to the given constraints.

Now let us convert the given inequalities into equations.

We obtain the following equation

The further explanation of the same is given below:

The region represented by x â€“ 2y â‰¤ 0:

The line x - 2y = 0 meets the coordinate axes at origin and slope of the line is . We will construct a line passing through origin and whose slope is . As point (1,1) satisfies the inequality. So, the side of the line which contains (1,1) is feasible. Hence, the solution set of the inequation x â€“ 2y â‰¤ 0 is the side which contains (1,1).

The region represented by â€“ 3x + y â‰¤ 4:

The line â€“ 3x + y = 4 meets the coordinate axes and (0,4) respectively. We will join these points to obtain the line -3x + y = 4. It is clear that (0,0) satisfies the inequation â€“ 3x + y â‰¤ 4. So, the region containing the origin represents the solution set of the inequation â€“ 3x + y â‰¤ 4.

The region represented by x â€“ y â‰¤ 6:

The line x â€“ y = 6 then meets the coordinate axes (6,0) and (0,-6) respectively. We will join these points to obtain the line x â€“ y = 6. It is clear that (0,0) satisfies the inequation x â€“ y â‰¤ 6. So, the region containing the origin represents the solution set of the inequation x â€“ y â‰¤ 6.

The graph for the same is given below:

The feasible region is region between line above BC and to the right of y axis as shown.

Feasible region is unbounded.

Corner points are A, B, C

Value of Z at corner points A, B, C and D â€“

So, maximum value of Z at corner points is 12 at C and minimum is -16 at A.

So, to check if the solution is correct, we plot 3 x-4 y>12 and 3 x-4 y<-16 for maximum and minimum respectively.

The region represented by 3 x-4 y>12

The line that is 3x â€“ 4y = 12 meets the coordinate axes (4,0) and (0,-3) respectively. When we join these points, we get the line 3x â€“ 4y > 12. It is clear that (0,0) does not satisfy the inequation 3x â€“ 4y > 12. So, the region not containing the origin represents the solution set of the inequation 3x â€“ 4y > 12.

The region represented by 3x â€“ 4y <-16:

The line 3x â€“ 4y = -16 meets the coordinate axes and (0,4) respectively. We will join these points to obtain the line 3x â€“ 4y <-16. It is clear that (0,0) does not satisfy the inequation 3x â€“ 4y <-16. So, the region not containing the origin represents the solution set of the inequation 3x â€“ 4y <-16.

We get the following answer:

Clearly, has no point inside feasible region, but passes through the feasible region.

Therefore, Z has no minimum value it has only a maximum value which is 12.

hello,

Yes you can appear for the compartment paper again since CBSE gives three chances to a candidate to clear his/her exams so you still have two more attempts. However, you can appear for your improvement paper for all subjects but you cannot appear for the ones in which you have failed.

I hope this was helpful!

Good Luck

Hello dear,

If you was not able to clear 1st compartment and now you giving second compartment so YES, you can go for your improvement exam next year but if a student receives an improvement, they are given the opportunity to retake the boards as a private candidate the following year, but there are some requirements. First, the student must pass all of their subjects; if they received a compartment in any subject, they must then pass the compartment exam before being eligible for the improvement.

As you can registered yourself as private candidate for giving your improvement exam of 12 standard CBSE(Central Board of Secondary Education).For that you have to wait for a whole year which is bit difficult for you.

Positive side of waiting for whole year is you have a whole year to preparing yourself for your examination. You have no distraction or something which may causes your failure in the exams. In whole year you have to stay focused on your 12 standard examination for doing well in it. By this you get a highest marks as a comparison of others.

Believe in Yourself! You can make anything happen

All the very best.

Hello Student,

I appreciate your Interest in education. See the improvement is not restricted to one subject or multiple subjects Â and Â we cannot say if improvement in one subject in one year leads to improvement in more subjects in coming year.

You just need to have a revision of all subjects what you have completed in the school. have a revision and practice of subjects and concepts helps you better.

All the best.

If you'll do hard work then by hard work of 6 months you can achieve your goal but you have to start studying for it dont waste your time its a very important year so please dont waste it otherwise you'll regret.

Yes, you can take admission in class 12th privately there are many colleges in which you can give 12th privately.
