Question

A sells a bicycle to b at a profit of 20% and b sells it to c at a profit of 25%. If c pays rs.1500, what did a pay for it?

a. Rs.825

b. Rs.1100

c. Rs.1000

d. Rs.1125

Answer 1

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.
