Question

Shikkan boy lends Rs.28000 for 4 years at $6\frac{1}{2}$ per cent per annum and Rs.65500 for 5 years at 8 per cent per annum. Find her total earning from these investments.

• A. $33480$
• B. $34440$
• C. $33240$
• D. $12220$

Answer 1

The correct option is A $33480$

$\Rightarrow$ Here $P=Rs.28000,T=4years$ and $R=6\frac{1}{2}\%=\frac{13}{2}\%$

$\Rightarrow$ $S.I.=\frac{P\times R\times T}{100}$

$\Rightarrow$ $S.I.=\frac{28000\times 13\times 4}{2\times 100}=Rs.7280$

$\Rightarrow$ Now, $P=Rs.65500,T=5years$ $R=8\%$

$\Rightarrow$ $S.I.=\frac{P\times R\times T}{100}=\frac{65500\times 8\times 5}{100}$

$\Rightarrow$ $S.I.=Rs.26,200$.

$\therefore$ Total earning from investment = $Rs.7280+Rs.26,200=Rs.33480$
