If 8 men complete a job in 12 days, then 4 men working at twice the speed will finish it in:
A6 days
B12 days
C24 days
D48 days
Answer & Solution
Correct answer: B. 12 days
1. Total work = 8 men × 12 days = 96 man-days at original speed.
2. 4 men at twice the speed = 4 × 2 = 8 effective men.
3. Time = 96 / 8 = 12 days.
