The correct Answer is:
To solve the problem, we need to analyze the information given about Wasim and Yunus's work efficiencies and their combined work time. ### Step-by-Step Solution: 1. **Understanding Efficiency**: - Let the efficiency of Yunus be \( E \). - Since Wasim is twice as efficient as Yunus, his efficiency will be \( 2E \). 2. **Combined Efficiency**: - When both work together, their combined efficiency is: \[ E + 2E = 3E \] 3. **Total Work**: - The total work done can be represented as \( W \). - The time taken by both to complete the work together is given as \( 7\frac{1}{2} \) days, which can be converted into an improper fraction: \[ 7\frac{1}{2} = \frac{15}{2} \text{ days} \] 4. **Using the Work Formula**: - The formula for work is: \[ \text{Work} = \text{Efficiency} \times \text{Time} \] - Therefore, the total work \( W \) can be calculated as: \[ W = \text{Combined Efficiency} \times \text{Time} = 3E \times \frac{15}{2} \] - Simplifying this gives: \[ W = \frac{45E}{2} \] 5. **Calculating Time Taken by Yunus**: - The time taken by Yunus to complete the work alone can be calculated using the formula: \[ \text{Time} = \frac{\text{Work}}{\text{Efficiency}} = \frac{W}{E} \] - Substituting \( W \): \[ \text{Time taken by Yunus} = \frac{\frac{45E}{2}}{E} = \frac{45}{2} = 22.5 \text{ days} \] 6. **Calculating Time Taken by Wasim**: - The time taken by Wasim to complete the work alone is: \[ \text{Time} = \frac{W}{2E} = \frac{\frac{45E}{2}}{2E} = \frac{45}{4} = 11.25 \text{ days} \] ### Conclusion: - **Quantity 1** (Time taken by Yunus) = 22.5 days - **Quantity 2** (Time taken by Wasim) = 11.25 days Now we compare the two quantities: - Quantity 1 (Yunus) is greater than Quantity 2 (Wasim). Thus, the answer is: - **Quantity 1 > Quantity 2**.

To solve the problem, we need to analyze the information given about Wasim and Yunus's work efficiencies and their combined work time. ### Step-by-Step Solution: 1. **Understanding Efficiency**: - Let the efficiency of Yunus be \( E \). - Since Wasim is twice as efficient as Yunus, his efficiency will be \( 2E \). ...
