Question

In what time will Rs 7,200 mount to Rs 8,820 at 9% per annum Simple Interest?

Answer 1

${\huge{\underline{\mathcal{\pink{Solution:-}}}}}$

$principal \implies 7200$

$amount \implies 8820$

$rate \implies 9\%$

$s.i. \implies amount - principal$

$\implies 8820 - 7200$

$\implies 1620$

$time \implies \frac{s.i. \times 100}{p \times r}$

$\implies \frac{1620 \times 100}{9 \times 7200}$

$\implies \frac{1620 \times \cancel{100}}{9 \times \cancel{7200}}$

$\implies \frac{\cancel{1620}}{\cancel{9} \times 72}$

$\implies \frac{180}{72}$

$therefore : time \: is \: \frac{180}{72} years$
