The average expenditure of a man for the first 6 month
is Rs.6000 and for the next 6 months is Rs.9000. If he saves 15000 in that year then find his average monthly income.Solution
Total expenditure in first 6 months = 6000 × 6 = Rs.36000 Total expenditure in last 6 month = 9000 × 6 = Rs.54000 Total income of the man in a year = 36000 + 54000 + 15000 = Rs.105000 So average income in a month = 105000/12 = Rs. 8750
