Question

The rate at which a sum becomes 4 times of itself in 16 years at simple interest is…..

• A. 300/17%
• B. 300/19%
• C. 300/11%
• D. 300/16%
• E. none of these

Answer 1

The correct option is D

300/16%

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

$4P$ = $P+I$

$I$ = $3P$

$3P$ = $\frac{P\times R\times 16}{100}$

$R$ = $\frac{300}{16}$
