Question

Assume there are four families in a country. The average per capita income of these families is Rs 5000. If the income of three families is Rs 4000, Rs 5000 and Rs 3000 respectively, what is the income of the fourth family? *

Answer 1

Answer:

8000

Explanation:

the total income of three familes =4000+5000+3000=12000

let the income of 4th family be X

so the given percapita income of these familes is 5000

then,

$\frac{12000 + x}{4} = 5000 \\ 12000 + x = 20000 \\ x = 20000 - 12000 \\ x = 8000$
