Time = 4.8 years

_________________

Given :

• principal = 20000
• amount = 32000
• rate = 12.5%

To find time:

Time

First finding S.I

S.I = 32000 – 20000

= 12000

$\bold{\LARGE{\underline{\underline{Explanation:–}}}}$

So ,

$S.I\:=\:\frac{P×R×T}{100}$

.

Now we have to find time:

$S.I\:=\:\frac{P\:×\:R\:×\:T}{100}$

$12,000\:= \:\frac{20000\:×\:12.5\:×\:t}{100}$

$12,000\:=\:\frac{250000\:×\:t}{100}$

$12,000\:=\:2500t$

$\frac{12000}{2500}\:=\:t$

$4.8 years \:=\:t$

$t\:=\:4.8\: years$

Therefore, time = 4.8 years
