Answer 1

Let us assume that the income of fourth family be x.

Income of first family =4000

Income of second family=7000

Income of third family =3000

Average income=5000

Average Income=Total income of families/Total population

5000=4000+7000+3000+x/4

5000*4=14000+x

20000=14000+x

20000-14000=x

x=6000 .

Hence,the income of fouth family is 6000 rupees.
