Question

By selling two chairs for 1200 each, a man gains 10% on one and loses 10% on the other. Find
his gain or loss percent in the whole transaction
​

Answer 1

Step-by-step explanation:

First table:-

Cost=1200

10%gain means

When CP is 100 sp =110

When CP is 1200 sp=(110*1200)/100

=1320

Second table:-

Cp=1200

10% loss means

When cp is 100 SP is 90

When cp is 1200 sp is (90*1200)/100=1080

Total cp is 1320+1080=2400

Total sp is 2400

Profit=2500-2400=100

Profit %=(100*100)/2400=4.167%
