Source Code

<!-- Javascript Program to Enter the P, T, R, and Calculate it's Simple Interest -->
<script type="text/javascript">

    var p, t, r, SI;
    
    // p = principal
    // t = time
    // r = rate
    // SI = simple interest
    
    // Calculate simple interest
    p = 15;
    t = 12;
    r = 12;
    
    SI = (p * t * r) / 100;

    document.write("Simple Interest = " + SI);
</script>

Output

Explanation

In this given program, we have pre-assigned the values of Principle, Time, and Rate the following 15, 12, and 12 then we applied the interest calculation formula to these given values.

Then, It will return the simple interest value of 21.6 the final output of this program.
