ATQ, For P: Cost price of item = Rs. x Marked price = 1.60 Γ x = Rs. 1.6x Selling price of item = Rs. (1.6x β 120) For Q; Cost price of item = Rs. (1.6x β 120) Marked price = 1.25 Γ (1.6x β 120) = Rs. (2x β 150) Selling price of item = 0.90 Γ (2x β 150) = Rs. (1.8x β 135) According to question: 1.8x β 135 β 1.6x + 120 = 135 Or, 0.2x = 150 Or, x = 750 Profit earned by 'P' = 1.6x β 120 β x = Rs. (0.6x β 120) = 0.6 Γ 750 β 120 = Rs.330
