Answer 2

Answer :-

• The simple interest is Rs 280.

Given :

• Principal = Rs 1000.
• Rate = 7% per annum.
• Time = 4 years.

To find :-

• The simple interest.

Step-by-step explanation :-

Detailed explanation of the solution :-

Let's understand!

• In this question, it has been given that the principal is Rs 1000, rate is 7% per annum and time is 4 years. We have to find the simple interest. For this, let's use a formula.

We know that :-

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

Here,

• Principal = Rs 1000.
• Rate = 7% per annum.
• Time = 4 years.

Substituting these values in the given formula,

$\tt SI = \dfrac{10 \not0 \not0 \times 7 \times 4}{1 \not0 \not0}$

Cutting off the zeroes,

$\tt SI = \dfrac{10 \times 7 \times 4}{1}$

Now let's multiply the remaining numbers.

$\tt SI = 10 \times 7 \times 4$

On multiplying,

$\tt SI = 280.$

-----------------------------------------------------------

• Hence, the simple interest is Rs 280.
