Question

Q. How much percent more than the cost price should a shopkeeper mark his goods so that after allowing a discount of 30% on the marked price, he gains 25%?

• A. 78.57%
• B. 77.25%
• C. 79.65%
• D. 80.25%

Answer 1

The correct option is A 78.57%

Explanation:

Let CP = 100

Then SP after 25% profit = 125

Marked price before 30% discount

$=125\times \frac{100}{70}=178.5770$

Required percentage $=178.57-100=78.57\%$
