Question
The average expenditure of a man for the first 6 month
is Rs.6000 and for the next 6 months is Rs.8000. If he saves 12000 in that year then find his average monthly income.Solution
Total expenditure in first 6 months = 6 × 6000 = Rs.36000 Total expenditure in last 6 month = 6 × 8000 = Rs.48000 Total income of the man in a year = 36000 + 48000 + 12000 = Rs.96000 So average income in a month = 96000/12 = Rs. 8000
