In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit ?

A. 30%

B.70%

C. 100%

D. 250%

Answer : B .70%


Explanation:


    Let Cost Price (C.P) = Rs. 100.

    Then, Profit = Rs. 320, Selling Price (S.P) = Rs. 420.

    New Cost Price (C.P) = 125% of Rs. 100 = Rs. 125

    New Selling Price (S.P) = Rs. 420.

    Profit = Rs. (420 – 125) = Rs. 295.

    Required Percentage = ( (295/420) x 100 )%

    = 70% (approximately).
