Question 7

Commercial Arithmetic

Two brothers invested a total sum of N5,000.00 on a farm project. The farm yield was sold for N15,000.00 at the end of the season. If the profit was shared in the ratio 2:3, what is the difference in the amount of profit received by the brothers?

  1. A.N2,000.00
  2. B.N4,000.00
  3. C.N6,000.00
  4. D.N10,000.00
Show the answer and explanation

Answer: A (N2,000.00)

Explanation

Profit = 15,000 − 5,000 = N10,000. The shares are 2/5 × 10,000 = N4,000 and 3/5 × 10,000 = N6,000, a difference of N2,000.
