A person sold 480 meters of cloth for Rs. 225 gaining thereby the cost of 72 meters. Find his gain percent?
Explanation:
Compute selling price of 1 m cloth = Rs. 225/480 = Rs. 15/32
Let CP of 1 m cloth be x. Hence, CP of 480 m = 480 x
Then gain = 72x
gain % = (72x)/(480x) × 100 = 15%
Hence, option (c).
