The average monthly expenditure of Anil for the first four months of a year was ₹6000 and for the next eight months it was ₹8200. He saved ₹12400 during the year. Find his average monthly income (in ₹) during the year.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 8500
Whatever Anil earned in the year was either spent or saved, so the year’s income is the total expenditure plus the saving; dividing by 12 gives the monthly average.
Expenditure in the first four months: \(4\times6000=24000\)
Expenditure in the next eight months: \(8\times8200=65600\)
Income for the year: \(24000+65600+12400=102000\)
Average monthly income: \(\frac{102000}{12}=8500\)
