Answer 1

Appropriate Question

Find the simple interest and total amount if the principle is ₹9450, rate is 10% and the time taken to return money back is 15 months.

Answer

Given :

Principle : ₹9450

Rate of interest : 10%

Time : 15 months

To find :

The simple interest and the total amount.

Solution :

We know that, to calculate the simple interest, we need the time in years format.

Time (in years) :

$\sf \dashrightarrow \dfrac{Number \: of \: months}{12}$

$\sf \dashrightarrow \dfrac{15}{12} = \dfrac{5}{4}$

Now, we can calculate the simple interest.

Simple interest :

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

$\sf \dashrightarrow \dfrac{9450 \times 10 \times 5}{100 \times 4}$

$\sf \dashrightarrow \dfrac{189 \times 10 \times 5}{2 \times 4}$

$\sf \dashrightarrow \dfrac{189 \times 5 \times 5}{2 \times 2}$

$\sf \dashrightarrow \dfrac{189 \times 25}{4} = \dfrac{4725}{4}$

$\sf \dashrightarrow \cancel \dfrac{4725}{4} = 1181.25$

Now, we can find the total amount.

Total Amount :

$\sf \dashrightarrow Simple \: Interest + Principle$

$\sf \dashrightarrow 1181.25 + 9450$

$\dashrightarrow$₹$\sf 10631.25$

Hence, the simple interest and total amount are ₹181.25 and ₹10631.25 respectively.
