ATQ,
Let the cost price of product P be Rs. x Therefore, cost price of product Q = Rs. (5000 β x) Marked price of product P = Rs. 1.25x Selling price of product P = 0.9 Γ 1.25x = Rs. 1.125x Marked price of product Q = Rs. 1.4(5000 β x) Selling price of product Q = 0.8 Γ 1.4(5000 β x) = Rs. 1.12(5000 β x) According to the question, 1.12(5000 β x) β 1.125x = 620 Or, 5600 β 1.12x β 1.125x = 620 Or, 2.245x = 4980 Or, x = 2218 Required difference = (5000 β x) β x = 5000 β 2x = Rs. 564
