Answer 2

Given,

Principal = 800/-

Rate = 6% per month

Time = 9 months

To find,

The simple interest.

Solution,

The simple interest on the principal amount is 432 rupees.

We can simply solve the mathematical problem by the following procedure.

We know that,

Simple interest = $\frac{P*R*T}{100}$

where,

P = Principal amount

R = rate

T = time

Now,

Simple interest = $\frac{800*6*9}{100}$

                          = 8 x 6 x 9

                          = 432 rupee

Thus,

The simple interest is 432 rupees.
