Question

A vendor imported apples from Himachal for Rs. 4000. He sold fruits worth 1500 at 10% profit. At what profit per cent should he sell the remaining apples to gain 20% on the whole.

• A. 25%
• B. 30%
• C. 27.5%
• D. 26%
• E. None of the above

Answer 1

The correct option is D 26%

Let the profit from the remaining apples be equal to x%.
Then, $\frac{1500}{4000}\times 10\%+\frac{2500}{4000}\times x\%=20\%$
$\Rightarrow x=16.25\times \frac{8}{5}=26\%$
