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?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 27 days.
The total number of hours worked by 12 men in 24 days = 12 × 9 × 24 = 2592 hours.
The total number of hours worked by 8 men in 1 day = 8 × 12 = 96 hours.
The number of days required by 8 men to complete the same work = 2592 / 96 = 27 days.
Therefore, 8 men working for 12 hours a day can complete the same piece of work in 27 days.
The answer is 27 days.
