Given:-

Simple intrest is $1240. Rate is 4.00%. Time is 2 years.

To find:-

The principal amount.

The formula which relates Simple intrest, Rate, Time and Principal amount is,


I=prt

So from this the formula for p is,


p=(I)/(rt)

Subsituting the known values. we get,


\begin{gathered} p=(I)/(rt) \\ p=(1240)/(0.04*2) \\ p=(1240)/(0.08) \\ p=(124000)/(8) \end{gathered}

By simplifying the above equation. we get the value of p,


\begin{gathered} p=(124000)/(8) \\ p=(31000)/(2) \\ p=15500 \end{gathered}

So the principle amount value is 15500.
