How much percent above the cost price should a shopkeeper mark his goods so as to earn a profit of 32% after allowing a discount of 12% on the marked price ?

Answer : Option A

Explanation :

Let the C.P. be Rs. 100 and the marked price be Rs. x. $\therefore \quad x \times \frac{88}{100}=132$ $\Rightarrow x=\frac{132 \times 100}{88}=150$ i.e., more by $50 \%$ Alternative:

Required per cent $=\frac{25}{50} \times 100=50 \%$
