3 chairs and 2 tables cost Rs. 700 and 5 chairs and 3 tables cost Rs. 1100. What is the cost of 1 chair and 2 tables?

350

400

500

550

3c + 2t = 700 __________________(i)

5c + 3t = 1100 __________________(ii)

1c+2t=?

Multiply (i) by 3 and (ii) by 2 we get.

9c+6t=2100

10c+6t=2200

Subtracting both we get

c = Rs 100

And t=Rs 200

1c+2t=Rs 500
