Question
The average expenditure of a man for the first 8 month
is Rs.4000 and for the next 4 months is Rs.6000. If he saves 10000 in that year then find his average monthly income.Solution
Total expenditure in first 8 months = 8 × 4000 = Rs.32000 Total expenditure in last 4 month = 4 × 6000 = Rs.24000 Total income of the man in a year = 32000 + 24000 + 10000 = Rs.66000 So average income in a month = 66000/12 = Rs. 5500
