Question
If 24 workers can build a wall in 15 days, how many days will 8 workers take to build a similar wall?
Options
42 days
45 days
48 days
none of these
Solution
45 days
Explanation:
Time is taken by 24 workers to build a wall = 15 days
Time taken by 1 worker to build a wall = 24 × 15 = 360 days (clearly less workers will take more time to build a wall)
Time is taken by 8 workers to build a wall = `360/8` = 45 days
