A shopkeeper sells an article at a certain price. What is his gain or loss percent, if by selling it at 75% of that price, he loses 10%?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Gain, 20%
Let S.P be 100x and According to question,
if by selling it at 75% of that price, he loses 10% i.e
New S.P = 75x and C.P = C.P - 10% of C.P = 75x
CP = 75x × 100/90 = 83.333x
Gain % = (100 - 83.33) × 100/83.33
Gain % = 20%
