Question

A shopkeeper sold a T.V set for Rs17,940 with a discount of 12.5% and Gained 5%. If no discount is allowed then what will be his gain percent?

Answer 1

Let the cost price be $C$ and the marked price be $M$

According to question , $M\times \frac{7}{8}=C\times \frac{105}{100}$

i.e $M=C\times \frac{6}{5}$

So his gain percent without discount = $20$%
