    If the cost price of a certain object doubles, then the

    loss gets tripled of what it was initially. The initial loss % was ?
    A 0 % Correct Answer Incorrect Answer
    B 25 % Correct Answer Incorrect Answer
    C 75 % Correct Answer Incorrect Answer
    D 50 % Correct Answer Incorrect Answer

    Solution

    Let the cost price be x and selling price be y.
    Loss = x – y
    When the cost price doubles, the loss gets tripled.
    So it becomes like this, 2x – y = 3(x-y)
    => x = 2y
    Loss % = (loss/ C.P)× 100 = [(2y-y)/2y]× 100 = 50 %
