Answer 1

I=576
R=6% per annum
T=3 yrs
P=?
I=PTR/100
576=P×3×6/100
P=576×100÷18
P=3200 Rupees

Answer 2

The principal of Rs.3200 will be earned an interest of Rs.576.

Given,

Interest = Rs.576

Rate = 6%

Time = 3 years.

To Find,

Principal =?

Solution,

In this question, we will use the formula of simple interest.

S.I. = $\frac{P*R*T}{100}$.

Where,

P = Principal

R = rate of interest

T = time period.

Here, we have to find P.

I = Rs.576

T = 3 years

R = 6%

On putting the value, we get

$576=\frac{P*6*3}{100}$

P = $\frac{576*100}{6*3}$

P = Rs.3200.

The principal of Rs.3200 will be earned an interest of Rs.576.
