Answer 1

Given :

Principle : ₹25500

Rate of interest : 15%

Time : 2 years 6 months

To find :

The total amount paid to his friend after the time.

Solution :

First, we'll find the simple interest.

Simple interest :

$\sf \dashrightarrow Simple \: Interest = \dfrac{P \times R \times T}{100}$

$\sf \dashrightarrow \dfrac{25500 \times 15 \times 3}{100 \times 2}$

$\sf \dashrightarrow \dfrac{255 \times 15 \times 3}{1 \times 2}$

$\sf \dashrightarrow \dfrac{255 \times 15}{2}$

$\sf \dashrightarrow \cancel \dfrac{3825}{2} = 1912.5$

Now, we can find the total amount.

Total Amount :

$\sf \dashrightarrow Simple Interest + Principle$

$\sf \dashrightarrow 1912.5 + 25500$

$\dashrightarrow$₹$\sf 27412.5$

Hence, the total amount to be returned back to his friend is ₹27412.5.
