Question

find the compound interest on 5000 rupees for 3 years at 12% per annum compounded annually​

Answer 1

$amount= \: p (1 + \frac{12}{100} )^{3}$

$amount= \: 5000 ( \frac{112}{100} )^3$

$a= \: 5000 × \frac{ 112^3 }{ 100^3}$

$a= \frac{175616}{25}$

$a=7024.64$

so amount is 7024.64

now C.I. is

=amount-principal

=7024.64-5000
=₹2024.64
