Question 15

'A' sells goods to 'B' at 25% profit for Rs.300. 'B' sells it to 'C' at 10% loss. In this sale, C's costprice is equal to what percent of A's cost price?

Solution

A's SP = 300 rs = B's CP

P% = 25%

therefore = A's CP = Then C = {100/(100+p)} x SP

HENCE = (100/(100+25))*300 = 240 rs

now , 'B' sells it to 'C' at 10% loss

SP of B = SP = {(100-L)/100} x CP

SP = {(100-10)/100} x 300 = 270 RS

C's costprice is equal to of A's cost price % = (270/240)*100 = 225/22 = 112.5%
