Correct Answer

D

Explanation

Let's assume the father's monthly income is represented by "x".The total allowance given to the three children is 20% of the father's monthly income, which is 0.2x.The second child received N3,000, which is 25% of the total allowance. So, we can set up the equation:0.25 * 0.2x = N3,000Simplifying the equation:0.05x = N3,000Dividing both sides of the equation by 0.05:x = N3,000 / 0.05x = N60,000Therefore, the father's monthly income is N60,000.
