Answer 2

Given :

principal=4000

rate 6%

time = 3 years

To Find :

Compound interest

Solution:

Principal=4000

Rate of interest in decimals = 6% =0.06

Time = 3 years

Formula:

$A=P(1+r)^t$

Where

A= Amount

P = principal

r = rate of interest

t = time

So,$A=4000(1+0.06)^3$

A=4764.064

Compound interest = Amount - Principal = 4764.064 -4000 = Rs.764.064

Hence The compound interest is Rs.764.064
