At what rate would a sum of N100.00 deposited for 5 years raise an interest of N7.50?

A.

1/2 %

B.

2(1/2)%

C.

1.5%

D.

25%

Correct Answer: 1.5%

Explanation

Interest I = PRT/100 ∴ R = (100n×n1)/(100 × 5) = (100 × 7.50)/(500 × 5) = 750/500 = 3/2 = 1.5%

Interest I = PRT/100 ∴ R = (100n×n1)/(100 × 5) = (100 × 7.50)/(500 × 5) = 750/500 = 3/2 = 1.5%
