Rajnish bought an item at 25% discount on the printed price. He sold it at 10% discount on the printed price. What is his profit in percentage?
Let printed price be 100.
Rajnish bought it at 25% discount, C.P of Rajnish = 75% of 100 = 75.
He sold it at 10% discount on printed price, S.P of Rajnish = 90% of 100 = 90
Hence, Rajnish, profit% = $$\ \frac{\ 90-75}{75}\times\ 100=20%$$.
The answer is option D.
