Question

A sum of RS 4000 is lent for 5 years at the rate of 15% per annum. Find the interest.

Answer 1

intrest =ptr/100
4000×5×15/100=3000 ans

Answer 2

Given,

A sum of RS 4000 is lent for 5 years at the rate of 15% per annum.

To Find,

The simple interest =?

Solution,

We can solve the question as follows:

It is given that a sum of Rs. 4000 is lent for 5 years at the rate of 15% per annum. We have to find the simple interest.

$Principal\: amount= Rs.\: 4000$

$Time = 5\: years$

$Rate = 15$%

The formula for simple interest is given as:

$Simple interest = \frac{PRT}{100}$

Where,

$P = Principal\: amount$

$R = Rate\: of\: interest$

$T = Time$

To find the simple interest, we will substitute the given values in the above formula,

$S.I. = \frac{4000*15*5}{100}$

      $=40*15*5$

      $= Rs.\: 3000$

Hence, the simple interest is equal to Rs. 3000.
