Leia Aguirre · Answer 1

Answer: Rs8000

Explanation:

Total income of 4 families is 6000 x4 = Rs24,000

Total income of 3 families

4000 + 7000 + 5000 = 16,000

4th family income = 24000 - 16000 = Rs8000

Chloe Petersen · Answer 2

8000/-

Explanation:

Let the income of the fourth family be X

4000 + 7000 + 5000 + x / 4 = 6000

Cross multiply

16000 + X = 24000

Collect like terms

X = 8,000

The income of the fourth family is 8,000
