A sells a camera to B at profit of 20% and B sells it to C at a profit of 25%. If C pays Rs 450, what price did A pay for the camera ?

A . Rs 300

B . Rs 350

C . Rs 400

D . Rs 450

Answer : A . Rs 300


Explanation:

    Let cost price for A = Rs. 100.
    SP for A = CP for B = 100 + 20% of 100 = 120.
    SP for B = CP for C = 120 + 25% of 120 = 150.

    Given,
    CP for C = 450
    So,
    150 = 450
    1 = 450/150
    100 = (450 *100)/150 = Rs. 300.
    CP for A = Rs. 300.
