Question
The selling price of 12 jackets is equal to the cost
price of 15 jackets. Find the percentage of profit earned on selling a jacket.Solution
ATQ, Let the cost price of a jacket = Rs. 'B' Then, cost price of 15 jackets = B × 15 = Rs. '15B' So, selling price of a jacket = (15B/12) = '1.25B' So, percentage of profit earned on selling a jacket = {(1.25B - B) ÷ B} × 100 = 25% Alternate Solution 12SP = 15CP Therefore, (SP/CP) = (15/12) Required profit percentage = {(15 - 12)/12} × 100 = 25%
