A person sold an article at 20% profit on the selling price. After wards, when the cost price reduced by 10%, then he also reduced the selling price by 10%. His percentage of profit cost price will be

A) 30
B) 25
C) 22.5
D) 12.5

Correct Answer:


B) 25

Description for Correct answer:
Given:

20% profit on SP means = \( \Large \frac{1}{5} \)

20% profit \( \Rightarrow \)\( \Large \frac{10\rightarrow Profit}{50\rightarrow SP} \)

\( \therefore \)CP= SP - Profit

CP = 50 - 10 = 40

\( \therefore \) Profit % = \( \Large \frac{Profit}{CP} \times 100 \)

\( \Large =\frac{9}{36} \times 100 \)

= 25%
