• C. Coomar
• D. Dubey

Answer 1

The Correct Option is C

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. \[ \boxed{\text{Coomar}} \]

Answer 2

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. \[ \boxed{\text{Dubey}} \]

Answer 3

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. \[ \boxed{\text{Dubey}} \]

Answer 4

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. \[ \boxed{\text{Ahuja}} \]
