NCERT Solutions For Class 10 Maths Chapter 3 Exercise 3.6
NCERT Solutions for class 10 maths ex 3.6 Pair of Linear Equations in two variables is discussed here. These NCERT solutions are created by subject matter expert at Careers360 considering the latest syllabus and pattern of CBSE 2023-24. This ex 3.6 class 10 consists of two questions, each with subparts. The first is straightforward, requiring only direct substitutions of the mathematical formula, whereas the second involves word problems. In this exercise, the majority of the variables are in fractional form, meaning that they are nonlinear, since the variables are now infraction, we can’t take the value of the denominator as zero because it will be against the definition of the fraction.
NCERT Solutions for Exercise 3.6 Class 10 Maths Chapter 3 - Pair of Linear Equations in two variables These class 10 maths ex 3.6 solutions are designed as per the students demand covering comprehensive, step by step solutions of every problem. Practice these questions and answers to command the concepts, boost confidence and in depth understanding of concepts. Students can find all exercise together using the link provided below.

Q1(vii) Solve the following pairs of equations by reducing them to a pair of linear equations:
Answer:
Given Equations,
Let,
Now, our equation becomes
And
By Cross Multiplication method,
Now,
And,
Adding (3) and (4) we get,
Putting this value in (3) we get,
And Hence,
Q1(viii) Solve the following pairs of equations by reducing them to a pair of linear equations:
Answer:
Given Equations,
Let,
Now, our equation becomes
And
Now, Adding (1) and (2), we get
Putting this value in (1)
Now,
And
Now, Adding (3) and (4), we get
Putting this value in (3),
Hence,
Q2(i) Formulate the following problems as a pair of equations and hence find their solutions: Ritu can row downstream 20 km in 2 hours, and upstream 4 km in 2 hours. Find her speed of rowing in still water and the speed of the current.
Answer:
Let the speed of Ritu in still water be x and speed of current be y,
Let's solve this problem by using relative motion concept,
the relative speed when they are going in the same direction (downstream)= x +y
the relative speed when they are going in the opposite direction (upstream)= x - y
Now, As we know,
Relative distance = Relative speed * time .
So, According to the question,
And,
Now, Adding (1) and (2), we get
Putting this in (2)
Hence,
Hence Speed of Ritu in still water is 6 km/hour and the speed of the current is 4 km/hour
Q2(ii) Formulate the following problems as a pair of equations and hence find their solutions: 2 women and 5 men can together finish an embroidery work in 4 days, while 3 women and 6 men can finish it in 3 days. Find the time taken by 1 woman alone to finish the work, and also that taken by 1 man alone.
Answer:
Let the number of days taken by woman and man be x and y respectively,
The proportion of Work done by a woman in a single day
The proportion of Work done by a man in a single day
Now, According to the question,
Also,
Let,
Now, our equation becomes
And
By Cross Multiplication method,
So,
