By selling 36 m of jute, a shopkeeper gains an amount equal to the selling price of 12 m of jute. Find the gain percentage.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 50%
SP of 36m = CP of 36m + SP of 12m
⇒ SP of 24m = CP of 36m
⇒ SP/CP = 36/24 = 3/2
If the CP of 1 m jute is Rs. 2, then it's SP is Rs. 3
So, profit = Re 1
Profit % = (1/2) × 100 = 50%
