Madhya Pradesh Police Exam Model Paper 5

Given:
Total number workers = 200
Scheduled to end within 250 days
After 30 days 20 workers leave the job
Concept used:
Total work = Total workers × Time
Calculations
Total work = 200 × 250 = 50000
Work done by 200 workers in 30 days = 200 × 30 = 6000
Remaining work = 50000 – 6000 = 44000
Remaining workers = 200 – 20 = 180
Time taken by 180 workers to finish the remaining work = 44000/180 ≈ 245 days
∴ Time taken to complete the remaining work by 180 workers is 245 days
