By selling an article at ¹¹⁄₂₅ of its selling price, a shopkeeper loses 34%. If he sells it at 80% of its original selling price, then his profit percentage is:

A28%
B20%
C30%
D25%

Correct answer: B

Explanation

Let the original SP = 100. (11/25) × 100 = 44 and this is 66% of CP, so CP = 66.67. At 80% of SP: 80 against CP 66.67, so profit = 13.33/66.67 = 20%.
