Answer:

Answer:p = Principal; n= Years; r= Rate of Interest

n here is 2 years and r is 20% per annum

Simple Interest (S) = (p*n*r)/100 = (p*2*20)/100 = 40p/100 = 0.4p

Compound Interest (C) = [p*(1+(r/100)^n)] -p = [p*(1+0.2)^2]-p = 1.44p - p = 0.44p

0.44p = 0.4p+96 ===> 0.04p = 96.00 ===> p = 96.00/0.04 = 2400

I hope it helps...
