Question

Find amount and comPound interest p-2000, r-5, n-2

Answer 1

Amount=P(1+R/100)^n
=2000(1+5/)^2
=2000* 21/20* 21/20
=5* 441
=₹2205
CI=A-P
=₹(2205-2000)
=₹205

Answer 2

compound interest = I,. A=I+P

I+p=p(1+r÷100)
I=2000(1+5÷100)^2- p
=2000(1+1÷20)^2-1
=2000 into 441÷400-1
=2000 into 41÷400
=5into 41
= 205
