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 7000 and Rs
3000 respectively, what is the income of the fourth family?​

Answer 1

Answer:

6000

Explanation:

Let income of fourth family be x.

Average income of four families=(4000+7000+3000+x) /4

5000=(14000+x) /4

14000+x=20000

x=6000

Answer 2

Answer:

Answer: d. Rs 6000

Answer: d. Rs 6000(4000+7000+3000+x) ÷ 4 = 500014000+x = 5000 × 4

Answer: d. Rs 6000(4000+7000+3000+x) ÷ 4 = 500014000+x = 5000 × 4x = 20000-14000

Answer: d. Rs 6000(4000+7000+3000+x) ÷ 4 = 500014000+x = 5000 × 4x = 20000-14000x = 6000
