Question

find the simple interest on Rs. 800 for 15 months at 12% p.a.​

Answer 1

The simple interest for principal = Rs. 800, time = 15 months and rate of interest = 12 p.a. is Rs. 120.

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

Let's understand a few concepts:

To calculate the simple interest we will use the following formula:

$\boxed{\bold{Simple \:Interest = \frac{Principal \times Time \times Rate}{100} }}$

To convert months to years we will use the following conversion rate:

$\boxed{\bold{1 \:month= \frac{1}{12} \:calender \:year}}$

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

Let's now solve the given problem:

The sum of money i.e., Principal = Rs. 800

The no. of years i.e., Time = 15 months = 15 / 12 years

The rate of interest i.e., Rate = 12% p.a.

Therefore, by substituting the given values in the above formula of simple interest, we get,

The simple interest is,

= $\frac{800 \: \times\: \frac{15}{12} \: \times\: 12}{100} }}$

= $8 \: \times\: \frac{15}{12} \: \times\: 12$

= $8 \: \times\: 15$

= $\bold{Rs.\:120}$

Thus, the simple interest is Rs. 120.
