    D Rs.720 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the original cost price be Rs. x Original selling price = 1.15x New cost price = 0.75x (25% less) New selling price = 0.7 × 0.75x = 0.525x (30% loss on new cost price) Difference in earnings = 1.15x – 0.525x = Rs. 280 ⇒ 0.625x = 280 ⇒ x = 280 / 0.625 = Rs. 448
