A shopkeeper cheats to the extent of 10% while buying and selling by using false weights. What is his total profit?
A
20%
B
21%
C
22%
D
25%
Correct Option:
C
Explanation
Using the false weights literally, the shopkeeper receives 110 units while buying for the price of 100 units, then gives only 90 units while selling for the price of 100 units. The gain is 110/90 − 1 = 22.22%, so 22% is the closest option.
