Twelve men working for 9 hours a day complete a piece of work in 24 days. In how many days can 8 men working for 12 hours a day complete the same piece of work?
A.27 days✓ Correct
B.21 days
C.24 days
D.28 days
Explanation
Total work = 12 × 9 × 24 = 2592 man-hours. For 8 men working 12 hours/day: days = 2592 / (8 × 12) = 2592/96 = 27 days.
