Show answer & explanation
Correct answer: A
Explanation
The correct answer in option 1 i.e. 33,335
Total expenditure of 12 months = Rs.18600 × 3 + Rs.21750 × 4 + Rs.22840 × 5
⇒ Rs.55800 + Rs.87000 + Rs.114200 = Rs.257000
Income = Savings + Expenditure
Income for the year = Rs.143020 + Rs.257000 = Rs.400020
The average monthly income = 400020/12 = Rs.33335
