Question
The average expenditure of a man for the first 9 month
is Rs.5000 and for the next 3 months is Rs.8000. If he saves 12000 in that year then find his average monthly income.Solution
Total expenditure in first 9 months = 9 × 5000 = Rs.45000 Total expenditure in last 3 month = 3 × 8000 = Rs.24000 Total income of the man in a year = 45000 + 24000 + 12000 = Rs.81000 So average income in a month = 81000/12 = Rs. 6750
