Answer 1

Answer:

6 men and 8 boy shall take 10 days to complete it

Answer 2

Answer:

3 men can do work in 20 days

so 1 men can do same work in 20*3 = 60 days

so 1 men can do 1/60 part of the work in 1 day is.

following the same for 6 boys,

1 boy can do 1/120 part of the work in one day.

now as per the question we have 6 men and 8 boys.

so 6 men can do 6*1/60  = 1/10 part of the work in  one day.

and 8 boys can do 8*1/120 = 1/15 part of the work in one day

so 6 men and 8 boys together can do 1/10 + 1/15 = 5/30 = 1/6 part of the work in one day

so 1/ 6 part of the work in one day

so it will take 6 days to complete the work when 6 men and 8 boys together works.

so the ans is 6 days,
