Question

The ratio of the cost price and selling price of a bulb is 20: 25. What is the profit percentage?

A.

20 percent

B.

25 percent

C.

15 percent

D.

30 percent

Correct option is B

Given:
Cost Price (C.P) : Selling Price (S.P) = 20:25
Formula Used:
Profit % = [(S.P - C.P) / C.P]×100
Solution:
Let the cost price (C.P) = 20x and selling price (S.P) = 25x.
Profit = S.P - C.P = 25x - 20x = 5x
Profit percentage = (5x / 20x)×100 = 25%
Therefore, the profit percentage is 25%.
