Verified Answer
If 20 men or 24 women or 40 boys can do a job in 12 days working for 8...
Amount of work done by 20 men = 24 women = 40 boys
or amount of work done by 1 man = 1.2 women = 2 boys.
The man hours required to complete the new task = 4 times the man hours required to complete the old task. (As the new task is 4 times as big as the old task)
So, the new task is 20 x 12 x 8 x 4 men hours task.
Let 'n' be the number of men required to complete the new task.
Equating the men hours of task, we get 20 x 12 x 8 x 4 = n x 5 x 12. Or n = 128.
The new task will require 128 men, if only men worked on the task to complete it.
However, the problem states that 6 women and 2 boys are working on the job.
6 women are the equivalent of 6/1.2 = 5 men and 2 boys = 1 man.
i.e., the equivalent of 5 + 1 = 6 men are already working on the project.
Therefore, 122 more men are required to work with 6 women and 2 boys to complete the task.
or amount of work done by 1 man = 1.2 women = 2 boys.
The man hours required to complete the new task = 4 times the man hours required to complete the old task. (As the new task is 4 times as big as the old task)
So, the new task is 20 x 12 x 8 x 4 men hours task.
Let 'n' be the number of men required to complete the new task.
Equating the men hours of task, we get 20 x 12 x 8 x 4 = n x 5 x 12. Or n = 128.
The new task will require 128 men, if only men worked on the task to complete it.
However, the problem states that 6 women and 2 boys are working on the job.
6 women are the equivalent of 6/1.2 = 5 men and 2 boys = 1 man.
i.e., the equivalent of 5 + 1 = 6 men are already working on the project.
Therefore, 122 more men are required to work with 6 women and 2 boys to complete the task.
