If 24 men can build a wall in 6 days, then how many days will 36 men take to build a wall of the same type and of double the length?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8.
Total work = 24 × 6 = 144 units
Double the wall ⇒ work doubles = 144 × 2 = 288 units
Time taken by 36 men = 288/36 = 8 days
