Question
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.Solution
According to the question, SP of 36 m = CP of 36 m + SP of 12 m ⇒ SP of 24 m = CP of 36 m So, SP/CP = 36/24 or 3/2 So, if CP of 1 m jute is Rs. 2 then its SP is Rs. 3 So, profit = Rs. 1 Profit % = (1/2) × 100 ⇒ 50% ∴ The gain percentage is 50%.
