Hey...!!!

S.I = 904
Time = 5 years
Rate of interest per annum = 7%

Principal = S.I x 100 / R x T
= 904 x 100 / 7 x 5
= 2582.85714

Answer 2

Given:

Simple Interest=Rs.904

Time=5 years

Rate=7% p.a.

To find:

The amount of principal

Solution:

The amount of principal is Rs. 2,582.85.

We can find the principal by taking the given steps-

We know that simple interest is the product of the amount of principal, rate of interest, and time in years divided by 100.

So, simple interest=Principal×Rate×Time/100

We are given that the simple interest=Rs.904, for 5 years at the rate of 7% p.a.

Let the amount of principal be P.

On putting the values, we get

904=P×7×5/100

904=P×35/100

904=P×7/20

904×20/7=P

129.14×20=P

P=2,582.85

The principal=Rs. 2,582.85.

Thus, the amount of principal is Rs. 2,582.85.
