Answer:

Let x be marks obtained by Ravi in the third test.

The student should have an average of at least 60 marks.

the student should have minimum marks of 35 to have an average of 60

Answer:

Sunita’s marks in the first four examinations are 87, 92, 94 and 95.

Let x be marks obtained in the fifth examination.

To receive Grade ‘A’ in a course, one must obtain an average of 90 marks or more in five examinations.

Thus, Sunita must obtain 82 in the fifth examination to get grade ‘A’ in the course.

Answer:

Let x be smaller of two consecutive odd positive integers. Then the other integer is x+2.

Both integers are smaller than 10.

Sum of both integers is more than 11.

We conclude and and x is odd integer number.

x can be 5,7.

The two pairs of consecutive odd positive integers are .

Answer:

Let x be smaller of two consecutive even positive integers. Then the other integer is x+2.

Both integers are larger than 5.

Sum of both integers is less than 23.

We conclude and and x is even integer number.

x can be 6,8,10.

The pairs of consecutive even positive integers are .

Answer:

Let the length of the smallest side be x cm.

Then largest side = 3x cm.

Third side = 3x-2 cm.

Given: The perimeter of the triangle is at least 61 cm.

Minimum length of the shortest side is 9 cm.

[ * Hint * : If x is the length of the shortest board, then , and are the lengths of the second and third piece, respectively. Thus, and ].

Answer:

Let x is the length of the shortest board,

then and are the lengths of the second and third piece, respectively.

The man wants to cut three lengths from a single piece of board of length 91cm.

Thus,

if the third piece is to be at least 5cm longer than the second, than

We conclude that and .

Thus , .

Hence, the length of the shortest board is greater than equal to 8 cm and less than equal to 22 cm.
