Question
A man purchased 36 pens in a certain amount and sold 27
pens in the same amount. The percentage of gain is:Solution
Let the CP of 36 be ‘x’ Then 1 pen = x/36 SP of 27 = x 1 pen = x/27 Then profit = (x/27) – (x/36) On solving we get x = 9 Then Gain % will be = [9x/(27×36)/(x/36)] × 100 = 33(1/3)%
