Explanation:
Let's assume the cost of a chair = Rs. x
And the cost of a Dining Table = Rs. y
so as per question
2x + y = 700 ..... (1) Multiply by 2
x + 2y = 800 ..... (2)
then
4x + 2y = 1400 ..... (3)
x + 2y = 800 ..... (4)
Get the value of x and y by solving equation (3) & (4)
x = 200 & y = 300
Cost of M chairs and M Dining Tables
=> M(x + y) = 30,000 <
=> M * 500 = 30,000
=> M = 60
