Question
The selling price of 5 bags is equal to the cost price
of 8 bags. Find the percentage of profit earned on selling a bag.Solution
ATQ, Let the cost price of a bag = Rs. 'A' Then, cost price of 8 bags = A × 8 = Rs. '8A' So, selling price of a bag = (8A/5) = '1.6A' So, percentage of profit earned on selling a bag = {(1.6A - A) ÷ A} * 100 = 60% Alternate Solution 5SP = 8CP Therefore, (SP/CP) = (8/5) Required profit percentage = {(8 - 5)/5} × 100 = 60%
