Step-by-step explanation:
if number of days at work is same
so we can equate directly
20 men = 25 boys
4 men = 5 boys
1 boy = 4/5 men
10 boys = 4/5 * 10 men
10 boys = 8 men
as 20 men completed work in 24 days
1 mam completes a work in = 24*20 = 480 days
16 men + 10 boys = ?
16 men + 8 men = 24 men
work = 24* 20 / 24 = 20 days
thus, 16 men and 10 boys do the whole work in 20 days
