Question

By selling a watch for ₹720,ravi loses 10%. At what price should he sell it in order to gain 15%​

Answer 1

Answer:

1st step find the cost price

SP=720

LOSS %=10

we have

SP=CP-LOSS% ON CP

or,720=x-10%on x(let cp=x)

or,x=800=CP

NOW FIND THE SP FROM SUCH CP AND PROFIT

SP=CP+PROFIT% ON CP

or,sp=800 +15%on 800

hence SP=920
