Explanation:

Average monthly income = Rs.10,000
So, total monthly income of the family of 5 = Rs.50,000
If one person's income increases by Rs.1,20,000 per year, his/her monthly income increases by Rs.10,000.
So, total monthly income now becomes = Rs.60,000
So, average monthly income now becomes 60/5 = Rs.12,000.
