Answer» Solution Let the original sum be Rs. x. Interest A paid to bank=$\frac{x\times8\times5}{100}$. Interest B paid to A=$\frac{x\times12\times5}{100}$. Therefore, profit made by A=Interest B paid to A-Interest A paid to bank. $800=\frac{20X}{100}$. $800=\frac{x}{5}$. $x=4000$. Hence, OPTION B is CORRECT.

Answer»

Solution

Let the original sum be Rs. x.
Interest A paid to bank=$\frac{x\times8\times5}{100}$.
Interest B paid to A=$\frac{x\times12\times5}{100}$.
Therefore, profit made by A=Interest B paid to A-Interest A paid to bank.
$800=\frac{20X}{100}$.
$800=\frac{x}{5}$.
$x=4000$.
Hence, OPTION B is CORRECT.
