Question

A book seller sold a book for rs 40 to make a profit of 15% in order to return a profit of 20% he should have sold it for??

Answer 1

Answer:

$rs. \frac{960}{23}$

Step-by-step explanation:

SP of a book = Rs. 40

Profit = 15%

CP = (SP×100)/(100+Profit%)

= 40×100/115

= 800/23

Profit = 20%

SP = CP(100+Profit%)/100

$= \frac{800 \times 120}{23 \times 100}$

= Rs. 960/23
