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?

Answer 1

S.P$=$Rs.$1500$

$B^{\prime }s$ profit $\%=25\%$

C.P for $B=\frac{100}{125}\times 1500=1200$

C.P for $B=$S.P for $A=1200$

Profit $\%$ for $A=20\%$

C.P for $A=\frac{100}{120}\times 1200=1000$ rupees.
