Question

A watch was sold at a loss of 10%.if it had been sold for Rs 10 more. it wold gain 10%. Find its cost price​

Answer 1

Less CP = 100

if it was sold at 10% loss it means it was sold at = 90

and he gain 10% more , it means it would be sold at = 110

increase in SP = 110-90 = 20

Given increase = 10

means it's = 10/20 = 1/2 times

that means our CP will also be (1/2) times = 100*1/2 = 50 (ans.)
