A man wishes to keep his money in a savings deposit at 25% compound interest…

A man wishes to keep his money in a savings deposit at 25% compound interest so that after three years he can buy a car for N150,000. How much does he need to deposit?
  • A.
    N112,000.50
  • B.
    N96,000.00
  • C.
    N85,714.28
  • D.
    N76,800.00
Correct Answer: Option D
Explanation

Amount A = P(1+r)n;
A = N150,000, r = 25%, n = 3.
150,000 = P(1+0.25)3 = P(1.25)3
P = 150,000/1.253 =N76,800.00
