Answer 1

Step-by-step 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 = 225

So,

150 = 225

1 = 225/150

100 = (225 *100)/150 = Rs. 150.

CP for A = Rs. 150.

Note: You can solve this question by taking CP of A = X as well.
