Hi,
75 boys can complete a work in 24 days or twice the work in 48 days: each boy 1/48*75 per day or 3 boys 1/48*25 per day
how many men need to complete twice the work in 20 days (2mens work=3boys)
2 men = 1/48*25 or 1 man 1/48*50 per day or 20/48*50 in 20 days
20/48*50 = 1/24*5 = 1/240. Would take 240 men to complete twice the work in 20 days
