Question

0n selling a mobile for 750 a shop keeper looses 10%for what amount should he sell it to gain 5%?

Answer 1

Find out the cost price first:
Here,
Sp= 750
Loss= 10%
So CP= 750 X 100 / 90
=> 2500/3
Now he has to gain 5% on the CP so, the new SP is (2500/3)X (105/100) = 875 Rs.
This is your answer.
