Answer:
₹800
Step-by-step explanation:
Total expenditure during the first 7 months period = 7*800 = ₹5600
Total expenditure during the next 5 months period= 5*800= ₹4000
Therefore, Total Expenditure = ₹(5600 + 4000) = 9600
Therefore, Average Monthly Expenditure = Total Expenditure / Total Time period = ₹9600/12 = ₹800
