Question

find the amount and compound interest on a sum of 15625 rupees at 4%per annum for 3 years compounded annually ​

Answer 1

first the formula of amount by compound interest is

$p(1 + \frac{r}{100}) {t}^{}$

this is the formula then we solve through this formula

p=15625₹,r=4percent per annum,time=3 years compounded annually.

$15625(1 + \frac{4}{100}) {3}^{}$

then

$15625(1 + \frac{1}{25}) {3}^{}$

then

$15652( \frac{26}{25}) {3}^{}$

then

$15625 \times \frac{26}{25} \times \frac{26}{25} \times \frac{26}{25}$

then

$15625 \times \frac{17576}{15625}$

then

$15625 \times 17576$

then

$274625000$

this is your amount then

Compound interest is

A-P

$274625000 - 15625$

then

$274609375$

this is your answer i hope it will help you bro/sis!!!!!
