• B. 4,100
• C. 3,700
• D. 3,950

Answer 1

Answer:

D. 3,950

Total expenditure for first three months = 2400 × 3 = Rs.7200 Total expenditure for five months = 3500 × 5 = Rs.17500 Total expenditure for four months = 4800 × 4 = Rs.19200 Total expenditure in a year = 7200 + 17500 + 19200 = Rs.43900 Total income in a year = 43900 + 3500 = Rs.47400 Average monthly income = 47400/12 = Rs.3950
