Question

Find the simple interest on:
(a) $ 2 LAKH for 5 months 10 DAYS at 1% per MONTH . Find the amount also.

Answer 1

Simple interest can be calculated by using the formula :

$\boxed{\bf{S.I=\frac{P\times R\times T}{100}}}$

Here : P = Principal Amount .

R = Rate of interest .

T = Time .

Given to us :

Principal = $ 2 lakhs .

Time = 5 months 10 days .

Rate = 1 % per month .

We know that on an average , 1 month = 30 days .

Hence 10 days = 1/3 month .

Thus 5 month + 10 days

= 5 + 1/3 months

= 16/3 months

$\mathsf{S.I=\dfrac{2\times \frac{16}{3}\times 1}{100}}\\\\\implies \mathsf{S.I=\dfrac{16}{150}}\\\\\implies \mathsf{S.I=\dfrac{8}{75}}\\\\\implies \mathsf{S.I=0.1067}$ .

The simple interest is 0.1067 lakhs .

Amount = Interest + Principal .

⇒ Amount = 2 lakhs + 0.1067 lakhs

⇒ Amount = 2.1067 lakhs .
