    A Rs.3200 Correct Answer Incorrect Answer
    B Rs.2200 Correct Answer Incorrect Answer
    C Rs.4000 Correct Answer Incorrect Answer
    D Rs.3,645 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the cost price of watch  'A' be Rs. 'x' Therefore, marked price of watch 'A' = 1.20 × x = Rs. '1.2x' ATQ, 1.2x + x = 11000 Or, 2.2x = 11000 Or, x = (11000/2.2) = 5000 Marked price of watch 'A' = 1.2x = 1.2 × 5000 = Rs. 6,000 Selling price of watch  'A' = 0.9 × 6000 = Rs. 5,400 Similarly, selling price of watch  'B' = Rs. 9,045 Required difference = 9045 - 5400 = Rs. 3,645
