E Correct answer
Explanation

16 men × 40 = 640 man-days. Converting: 20 women = 16 men, so 1 woman = 0.8 man. 32 boys = 16 men, so 1 boy = 0.5 man. Combined team: 8 men + 30(0.8) + 16(0.5) = 8 + 24 + 8 = 40 men equivalent. Days needed = 640/40 = 16 days. Option A would require 42.7 man-equivalents, Option B would require 35.6.
