The data points in the figure below represent monthly income and expenditure data of individual members of the Ahuja family (■), the Bose family (□), the Coomar family (⃝), and the Dubey family (•). For these questions, savings is defined as:
Savings = Income−Expenditure
The line in the figure indicates Income = Expenditure.

The Correct Option is C
Solution and Explanation
From the graph, the Coomar family (○) points are all located in the lower half of the income axis, around the 1000–2000 income range.
Comparing across families: - Ahuja (■) and Dubey (●) have multiple members with incomes above 3000.
- Bose (□) members are generally around 2000–2500.
- Coomar (○) members are consistently lower, making their average income the lowest. \[ \boxed{\text{Coomar}} \]

The Correct Option is D
Solution and Explanation
The Dubey family (●) has members plotted farthest to the right on the expenditure axis, with expenditures close to 3000 and above.
Other families' points are generally to the left, meaning lower expenditures on average. \[ \boxed{\text{Dubey}} \]

Solution and Explanation
Savings = Income – Expenditure.
The Dubey family (●) has many points close to or even below the diagonal Income = Expenditure line, meaning their savings are minimal or negative.
Other families have points further above the line, indicating higher savings. \[ \boxed{\text{Dubey}} \]

The Correct Option is A
Solution and Explanation
Savings = Income – Expenditure.
The highest savings corresponds to the point farthest above the diagonal line.
This point belongs to the Ahuja family (■), with high income (~3000) and low expenditure (~1000), giving savings around 2000. \[ \boxed{\text{Ahuja}} \]
