Answer 2

Cost of 1 table is Rs.130

Cost of 1 chair is Rs.50

Step-by-step explanation:

Let the cost of 1 chair = x

Let the cost of 1 table = y

Cost of 5 chairs = 5x

Cost of 3 chairs = 3x

Cost of 2 tables = 2y

Cost of 3 tables = 3y

We are given that 5 chairs and 2 tables cost rs 750

So, 5x+2y= 750  --- 1

We are given that 3 chairs and 3 tables cost rs 540

So,3x+3y=540 ---2

Plot 1 and 2 on graph

5x+2y= 750 --- Blue line

3x+3y=540 --- Green line

The intersection point will provide the solution

So,Solution = (130,50)

So, Cost of 1 table is 130

Cost of 1 chair is rs.50
