Question

by selling a bicycle for his 16382 Sita loses 9% at what price should he sell it to make a profit of 15%

Answer 1

Given
Sp=16382

Loss%=9%

1 way to solve it

Cp=spx100/(100-loss%)

Cp=16382x100/(100-9)

Cp=1638200/91

Cp=18002.1978


Now he wants to sell it on profit if 15%
Then

Sp=cpx(100+profit%) /100

Sp=18002.1978 (100+15)/100

Sp=18002.1978x115/100

Sp=20702. 53


2nd way to solve

Sp= old Sp x (100+profit)/(100-loss%)

Sp=16382x115/91

Sp=20702.53
