A sum of money was invested at 8% per annum simple interest. If after 4 years the money amounts to N330.00. Find the amount originally invested

A.

N180.00

B.

N165.00

C.

N150.00

D.

N250.00

E.

N200.00

Correct answer is D

S.I = \(\frac{PTR}{100}\)

T = 4yrs, R = 8%, a = N330.00

330 - P = \(\frac{PTR}{100}\), A = P + I

i.e. A = P + \(\frac{PTR}{100}\)

330 = P + \(\frac{P(4) (8)}{100}\)

33000 = 32P + 100p

132P = 33000

P = N250.00
