Answer 1

To find the average monthly income of the family, calculate the total monthly income for the entire year by summing up the expenditures and subtracting the total savings. Then, divide the result by the number of months in the year.

Step-by-step explanation:

To find the average monthly income of the family, we need to calculate the total monthly income for the entire year. We can do this by summing up the expenditures for each period of the year, and then subtracting the total savings. Finally, we divide the result by the number of months in the year to get the average monthly income.

Step 1: Calculate the total expenditures for each period of the year: 6240 + 6780 + 7236 = 20256

Step 2: Subtract the total savings from the total expenditures: 20256 - 7080 = 13176

Step 3: Divide the result by the number of months in the year (12) to get the average monthly income: 13176 / 12 = 1098

Therefore, the average monthly income of the family is 1098 rupees.
