Answer 1

Step-by-step explanation:

Compound interest =>

Principal (1+ interest rate/100)^time - Principal

Let the principal be x.

$5712 = x(1 + \frac{4}{100})^{2} - x = >$

$5712 = x {(1.04)}^{2} - x = > 5712 =$

$x(1.0816) - x = > 5712 = 0.0816x$

$= > x = \frac{5712}{0.0816} = 70000$

So the sum on which we get 5712 ruppees as compound interest for 2 years at 4% interest rate per annum is 70000 ruppees. Hope it helps you.
