Expert Answer:

If we invest an amount of Rs. P for n yeras and at r% per annum at simple rate of interest then simple interest is calculated as Pnr/100.
For example,
P = Rs. 1000, r = 10% per annum, n = 2 yares then simple interest will be
Simple interest = 1000 × 10 × 2/100 = Rs. 200
 
If we invest an amount of Rs. P for n years and at r% per annum compounded annually then compound interest is calculated as          P(1 + r/100)n - P where 
A = P(1 + r/100)n
For example,
P = Rs. 1000, r = 10% per annum compounded annually for n = 2 years then amount we will get
A = 1000(1 + 10/100)2 = 1000(1 + 0.1)2 = 1000 × 1.12 = Rs. 1210
Compound interest = A - P = 1210 - 1000 = Rs. 210
 
From the above example we conclude that we get more interest if rate is compounded annually rather than on simple interest.
