SIMPLE INTEREST= 20% of 1000=200
200*5(years)=1000
now add 1000+1000=2000
COMPOUNDED= 20% of 1000=200
1000*1.20^4=2073

\(SI = P \times R \times T =\) \(1000 \times 0.2 \times 5 = 1000\)
\(CI = P[1+\frac{r}{n}]^{nt} = P[1+\frac{0.2}{1}]^{4(1)} = 1000[1.2]^4 = 2073.6\)
where
r = rate expressed in decimals
n = number of times compounded per year
t = number of years
Clearly Quantity B is greater
