Detailed Solution

The average income of the fourth family is Rs 7000.
The average per capita income is obtained by dividing the total income by the total population.
Thus, in this case, Average income

\times

4 = Total income
Total income of four families = 4

\times

6000 = 24,000
Total income of three families = 4000 + 7000 + 6000 = 17,000
Total income of the fourth family = 24,000 - 17,000 = 7,000
