    B Rs. 1,334 Correct Answer Incorrect Answer
    C Rs. 1,450 Correct Answer Incorrect Answer
    D Rs. 1,500 Correct Answer Incorrect Answer
    E Rs. 1,600 Correct Answer Incorrect Answer

    Solution

    Let the cost price of D be Rs. β€˜a’ Cost price of C = Rs. (a βˆ’ 400) Marked price of C = 1.45 Γ— (a βˆ’ 400) = Rs. (1.45a βˆ’ 580) Marked price of D = 1.2a Selling price of C = 1.45a βˆ’ 580 βˆ’ 200 = Rs. (1.45a βˆ’ 780) Selling price of D = 1.2a βˆ’ 150 Profit earned by C = 1.45a βˆ’ 780 βˆ’ a + 400 = Rs. (0.45a βˆ’ 380) Profit earned by D = 1.2a βˆ’ 150 βˆ’ a = Rs. (0.2a βˆ’ 150) ATQ, 0.45a βˆ’ 380 = 0.2a βˆ’ 150 + 100 Or, 0.45a βˆ’ 380 = 0.2a βˆ’ 50 Or, 0.25a = 330 Or, a = 1320 Marked price of C = 1.45 Γ— (1320 βˆ’ 400) = 1.45 Γ— 920 = Rs. 1,334
