    E All of I, II and III Correct Answer Incorrect Answer

    Solution

    ATQ, Marked price of watch 'X' = 150% of 18,000 = (1.5) x 18,000 = Rs. 27,000 Selling price of watch 'X' = 80% of 27,000 = (0.8) x 27,000 = Rs. 21,600 Profit earned on watch 'X' = Rs. 21,600 - Rs. 18,000 = Rs. 3,600 Marked price of watch 'Y' = 170% of 25,000 = (1.7) x 25,000 = Rs. 42,500 Selling price of watch 'Y' = 125% of 25,000 = (1.25) x 25,000 = Rs. 31,250 Discount offered on watch 'Y' = (11,250/42,500) x 100 = 26.47% Statement (I) is true. Statement (II) is false (the discount is 26.47%, not 20%). Statement (III) is true (Rs. 6,250 profit on watch 'Y' is more than Rs. 3,600 on watch 'X'). Hence, Both I and III is true
