Question

3 men or 5 boys can do
o puce of work in 12
days How long would
1 man and 2 boys take
to do the same work?​

Answer 1

Answer:

3 men do a work in 86 days.

So 1 man does 1/(3*86) = (1/258)th part of the work in a day.

And 12 men do (12/258)th part of the work in a day.

5 boys do a work in 86 days.

So 1 boy does 1/(5*86) = (1/430)th part of the work in a day.

And 11 boys do (11/430)th part of the work in a day.

Therefore 12 men and 11 boys do (12/258)+(11/430) = (20.72/430)+(11/430) = 31.64/430 = 1/13.59039191 th part of the work in a day.

Hence 12 men and 11 boys will complete the work in 13.59039191 days.
