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.
