Correct Answer: 4000

Step 1: Understand that the average income of the family is $5000 and there are 3 members in the family (father, mother, and child).
Step 2: Calculate the total income of the family by multiplying the average income by the number of family members: 5000 * 3 = 15000.
Step 3: The father earns $7000. To find the combined income of the mother and child, subtract the father's income from the total income: 15000 - 7000 = 8000.
Step 4: Now, to find the average income of the mother and child, divide their combined income by the number of them: 8000 / 2 = 4000.
