Question

a table cost 200 more than a chair the price of 2 tables and 3 chairs is 1400. find the cost of each

Answer 1

T=Tables C=Chairs

T=C+200
2T+3C=1400

2(C+200)+ 3(200)=1400
2C+400+600=1400
2C=400
C=200
T=C+200 T=200+200
T=400

Chairs=200 Tables= 400

Answer 2

Hi ,

Let the cost one chair = Rs x

cost of one table = Rs ( x + 200 )

cost of 2 tables and 3 chairs = Rs 1400

2( x + 200 ) + 3x = 1400

2x + 400 + 3x = 1400

5x = 1400 - 400

5x = 1000

x = 1000 / 5

x = 200

Therefore ,

cost of one chair = x = Rs 200

cost of one table = x + 200

= 200 + 200


= Rs 400

I hope this helps you.
