If $R s .3, 750$ amount to $R s .4, 620$ in $3$ years at simple interest, Find
The rate of interest.

Solution

We have,
$P = 3750$
$A = 4620$

We know that
$A = S . I + P$ and $S . I = \frac{P \times R \times T}{100}$

Therefore,
$\Rightarrow S . I = 870 = \frac{3750 \times R \times 3}{100}$
$\Rightarrow R = \frac{87000}{3750 \times 3} = 7.74 %$

Hence, this is the answer.

If Rs.3,750 amount to Rs.4,620 in 3 years at simple interest, Find The rate of interest.

We have,P=3750A=4620We know thatA=S.I+P and S.I=P×R×T100Therefore,⇒S.I=870=3750×R×3100⇒R=870003750×3=7.74%Hence, this is the answer.
