1. Mr. Jamal employed 50 workers to finish a work within 30 days. After 20 days he found out that only 50% work had been completed. How many additional workers would be need to finish the task in scheduled time?
- A. 40
- B. 40
- C. 40
- D. 40
Answer: Option B
Explanation:
Remaining days = 30 - 20 = 10 days
Remaining work = 100% - 50% = 50%
Now, 50% work can be completed in 20 days by 50 workers
So, 50% work can be completed in 10 days by 50 x 20 / 10 = 100 workers
Therefore, additional workers needed = 100 - 50 = 50
