Answer:
men and 12 boys finish the same work in 25.412 days.
Step-by-step explanation:
2 men work as much as 6 boys
So, 8 men work as much as 6/2 × 8 =24 boys work
And, 4 men work as much as 12 boys work.
Now, 8 men + 10 boys = 24 boys + 10 boys = 34 boys
4 men + 12 boys = 12 boys + 12 boys =24 boys
hence, 34 boys can complete a work in 36 days
24 boys can complete this work in (36/34 )×24 = 25.412 days or 25 days 10 hours (approx).
