A man invested N5,000 for 9 months at 4%. What is the simple interest?

A.
N150 
B.
N220 
C.
N130 
D.
N250
Correct Answer: Option A
Explanation
S.I. = (frac{P times R times T}{100})
If T = 9 months, it is equivalent to (frac{9}{12}) years
S.I. = (frac{5000 times 4 times 9}{100 times 12})
S.I. = N150
