If $P=Rs.37500$ and $R=18\%$, in what time will it amount to Rs.52250?

$I=\frac{PTR}{100}$

$I=\frac{375\times T\times 18}{100}\to \left(1\right)$

$522.50=375.00+I$

$I=147.50\to \left(2\right)$

$147.50\times 100=375\times T\times 18$

$14750=T\times 375\times 18$

$T=\frac{14750}{375\times 18}=\frac{14750}{6750}$

$=2.185$ years
