Answer 2

Given :

Principle : ₹66000

Total Amount : ₹72720

Time : 2 years

To find :

The rate of interest applied to the loan or investment.

Solution :

First, we should find the simple interest.

Simple interest :

$\sf \dashrightarrow Total \: Amount - Principle$

$\sf \dashrightarrow 72720 - 66000$

$\sf \dashrightarrow Rs.6720$

Now, we can find the rate of interest by the formula of simple interest.

Rate of interest :

$\sf \dashrightarrow SI = \dfrac{P \times R \times T}{100}$

$\sf \dashrightarrow 6720 = \dfrac{66000 \times R \times 2}{100}$

$\sf \dashrightarrow 6720 = \dfrac{132000 \times R}{100}$

$\sf \dashrightarrow R = \dfrac{6720 \times 100}{132000}$

$\sf \dashrightarrow R = \dfrac{672 \times 1}{132}$

$\sf \dashrightarrow R = \dfrac{672}{132}$

$\sf \dashrightarrow R = 5.09\%$

Hence, the rate of interest per annum at simple interest is 5.09%.
