The question you provided from the image is:

"The income of Mr. Dhull and Mr. Hussain are in the ratio 7:4, and their expenditure is in the ratio 2:1. If each saves ₹10,000, then Mr. Dhull’s expenditure is:"

### Step-by-step solution:

1. **Let the incomes of Mr. Dhull and Mr. Hussain** be \(7x\) and \(4x\) respectively.
2. **Let their expenditures** be in the ratio 2:1, so their expenditures are \(2y\) for Mr. Dhull and \(y\) for Mr. Hussain.
3. Since both save ₹10,000, their savings are given as:
   \[
   \text{Income} - \text{Expenditure} = \text{Savings}
   \]
   For Mr. Dhull: 
   \[
   7x - 2y = 10,000 \quad \text{(1)}
   \]
   For Mr. Hussain:
   \[
   4x - y = 10,000 \quad \text{(2)}
   \]

4. **Solve the system of equations**:

   From equation (2): 
   \[
   y = 4x - 10,000
   \]
   Substitute this value of \(y\) in equation (1):
   \[
   7x - 2(4x - 10,000) = 10,000
   \]
   Simplifying:
   \[
   7x - 8x + 20,000 = 10,000
   \]
   \[
   -x + 20,000 = 10,000
   \]
   \[
   -x = -10,000
   \]
   \[
   x = 10,000
   \]

5. **Find Mr. Dhull's expenditure**:
   Using \(x = 10,000\) in the equation for \(y\):
   \[
   y = 4(10,000) - 10,000 = 40,000 - 10,000 = 30,000
   \]
   Mr. Dhull’s expenditure is \(2y\):
   \[
   2y = 2 \times 30,000 = 60,000
   \]

### Final Answer:
Mr. Dhull’s expenditure is ₹60,000.

4. How can you generalize this solution for different income and expenditure ratios?
5. What is the total savings of both Mr. Dhull and Mr. Hussain combined?

### Tip:
When solving problems with ratios, it's always useful to define variables and set up relationships based on the given conditions (such as income, expenditure, and savings).

The income of Mr. Dhull and Mr. Hussain are in the ratio 7:4, and their expenditure is in the ratio 2:1. If each saves ₹10,000, then Mr. Dhull’s expenditure is:
