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?

• A. Rs 7500
• B. Rs 3000
• C. Rs 2000
• D. Rs 6000

Answer 1

The correct option is D Rs 6000

• 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.
