Answer 2

Hello friend
-----------------

Given:

Principal P= 4000Rs.

Rate of interest,R = 5%

Number of period N= 3year.

To find Compound Interest= ??

As we all know that,

Compound Interest= P(1+R/100)^N - P

Compound Interest= 4000(1+5/100)^3-4000

Compound Interest= 4000(105/100)^3-4000

Compound Interest = 4000*1157625/1000000-4000

Compound Interest = 4*1157625-4

Compound Interest= 4630496 For 3years.
