The average monthly income of a person in a certain family of 5 members is Rs. 1000. What will be the monthly average income of one person in the same family if the income of one person increased by Rs. 12,000 per year?
Answer and explanation
Correct answer A
The correct choice is: “Rs. 1200”
Total monthly income of the family = 5 × 1000 = Rs. 5000.
An increase of Rs. 12,000 per year = 12,000 ÷ 12 = Rs. 1000 per month. New total monthly income = 5000 + 1000 = Rs. 6000.
New average monthly income per person = 6000 ÷ 5 = Rs. 1200.
