Back to paper

A 15% discount is allowed by a tradesman. How much above the cost price (in percentage) must he mark his goods so as to gain 19%?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 40%.

CPMP=100−D100+P\frac{CP}{MP} =\frac{100 - D}{100 + P}

⇒ CP/MP = 85/119

⇒ CP/MP = 5/7

Now required percentage = [(7 - 5)/5] × 100

⇒ 40%
