Find at which rate per annum simple interest N525 will amount to N588 in 3 years.
  • A.
    3%
  • B.
    2%
  • C.
    5%
  • D.
    4%
Correct Answer: Option D
Explanation

I = A − P
= N588 − N525
∴I = N63
I = PRT ÷ 100
R = [100I ÷PT] R = [(100 × 63 ) ÷ (525 × 3)] = (6300 ÷ 1575) = 4
∴ The rate = 4 %
