Answer 1

total no. Of family=4

so

(4000+7000+3000+x)/4 = 5000

4000 +7000+3000+x=5000×4=20000

x=6000

Answer 2

Answer:

ANSWER

Per capita income is the total income of the country/state divided by the number of people in that country/state.

Here total four families. The average per capita income (5000) is equal to (4000+7000+3000+x) / 4

Income of fourth family is Rs. 20,000 - Rs. 14,000 = Rs. 6,000.
