Question

Find the simple interest when principal=Rs.1000, rate=4% per annum,
Time=3 years.​

Answer 1

Answer :-

• The simple interest is Rs 120.

To find :-

• The simple interest.

Step-by-step explanation :-

• In this question, the principal, rate and time have been given to us. We have to find the simple interest.

We know that :-

$\underline{\boxed{\sf SI = \dfrac{Principal \times Rate \times Time}{100}}}$

Where,

• SI = Simple Interest.

Here,

• Principal = Rs 1000.
• Rate = 4% per annum.
• Time = 3 years.

Substituting the given values in this formula,

$\rm SI = \dfrac{1000 \times 4 \times 3}{100}$

Cutting off the zeroes,

$\rm SI = \dfrac{10 \times 4 \times 3}{1}$

Now let's multiply the remaining numbers since we can't reduce them anymore.

$\rm SI = 10 \times 4 \times 3$

Multiplying the numbers,

$\overline{\boxed{\rm SI = Rs \: 120}}$
