Explanation

From given: 1 man's 1 day work = 1/44. Since 2 women = 1 man, 1 woman's work = 1/(44×2) = 1/88. Since 3 boys = 1 man, 1 boy's work = 1/(44×3) = 1/132. Combined work of 1 man + 1 woman + 1 boy = 1/44 + 1/88 + 1/132 = (3+1.5+1)/132 = 5.5/132 = 1/24. Therefore they complete the work in 24 days.
