Question

Find the time when the following are given.
Principal$=Rs500$
Rate $=7.5$ p.a
$I=Rs150$

Answer 1

As we know that,

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

Given:-

$S.I.=Rs.150$

$R=7.5\%$ per annum

$t=?$

$P=Rs.500$

Therefore,

$150=\frac{500\times 7.5\times t}{100}$

$\Rightarrow t=\frac{15000}{7.5\times 500}=4\text{years}$
