Question
A seller priced 40 items (each
having the same cost price) at 175% above their cost price. He sold 1/2th of these items with a 20% discount and the remaining half with a 60% discount. Calculate the total profit he made.Solution
ATQ,
Let the cost price of each item be Rs. '10a'. So, marked price of each item = 10a X 2.75 = Rs. '27.5a' Selling price of 20 item = 27.5a X 20 X 0.8 = Rs. '440a' Selling price of remaining 20 item = 27.5a X 20 X 0.4 = Rs. '220a' So, total selling price = 220a + 440a = Rs. '660a' And total cost price = 10a X 40 = Rs. '400a' Total profit = 660a - 400x = Rs. '260a' So, required % = (260a/400a) X 100 = 65%
