2175
Steps/Work
Explanation:
Total expenditure for the first 3 months = 3 × 1900 = 5700
Total expenditure for 4 months = 4 × 1550 = 6200
Total expenditure for 5 months = 5 × 1800 = 9000
Total expenditure and saving (which is income for one year)
= 5700 + 6200 + 9000 + 5200 = Rs. 25200
So, Average monthly income = 26100/12 = Rs. 2175
Answer B
Total expenditure for the first 3 months = 3 × 1900 = 5700
Total expenditure for 4 months = 4 × 1550 = 6200
Total expenditure for 5 months = 5 × 1800 = 9000
Total expenditure and saving (which is income for one year)
= 5700 + 6200 + 9000 + 5200 = Rs. 25200
So, Average monthly income = 26100/12 = Rs. 2175
Answer B
