Question

A sum of $Rs.9600$ is invested for $3$ years at $10\%$ per annum at compound interest, then find the interest due on the principal after $3$ years.(Input the greatest integer value)

Answer 1

Given : $P=Rs.9600$

$R=10\%$

$T=3years$

$C.I=P{(1+\frac{R}{100})}^T-P$

$C.I=9600{(1+\frac{10}{100})}^3-9600$

$C.I=12777.6-9600$

$C.I=Rs.3177.6$

Interest paid $Rs.3177$.
