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.
