Question

A sold an article to B at a profit 2.5% B sold the same article to C at loss 10 %. If c paid 9.90 for it how much did it cost to A​

Answer 1

Answer:

let the c.p of A is x

now,

s.p of A(C.P of B) = x *112.5/100

= 9/8x

Again,

s. p of B= 9/8x*90/100

= 81/80x

Again,

81/80x =9.90

x=9.77

Hence, the c. p of A = 9.77 rupees
