D. Can't determined

Answer

To find the average savings of A, B, and C, we can follow these steps:

### Step 1: Understand the given information
We know:
- Average salary of A, B, and C = ₹10,000
- Average expenditure of A, B, and C = ₹6,000

### Step 2: Calculate the total salary
Since the average salary of A, B, and C is ₹10,000, we can calculate the total salary by multiplying the average salary by the number of individuals (which is 3).

\[ \text{Total Salary} = \text{Average Salary} \times \text{Number of Individuals} = 10,000 \times 3 = ₹30,000 \]

### Step 3: Calculate the total expenditure
Similarly, we can calculate the total expenditure using the average expenditure.

\[ \text{Total Expenditure} = \text{Average Expenditure} \times \text{Number of Individuals} = 6,000 \times 3 = ₹18,000 \]

### Step 4: Calculate the total savings
Savings can be calculated by subtracting the total expenditure from the total salary.

\[ \text{Total Savings} = \text{Total Salary} - \text{Total Expenditure} = 30,000 - 18,000 = ₹12,000 \]

### Step 5: Calculate the average savings
Finally, we can find the average savings by dividing the total savings by the number of individuals.

\[ \text{Average Savings} = \frac{\text{Total Savings}}{\text{Number of Individuals}} = \frac{12,000}{3} = ₹4,000 \]

### Conclusion
The average savings of A, B, and C is ₹4,000.
