Question

2 chairs and one table cost Rs. 700 and 1 chair and 2 tables cost Rs 800. If the cost of m tables and m chairs Rs 30,000, then what is m equal to?

Answer 1

Let chair be denoted as x and table be denoted as y.
2x+y=700
X+2y=800
on solving both you get x=200 y=300
it is given that mx+my=30000
m(x+y)= 30000
m(200+300)=30000
m(500)=30000
m=60
