From I & II, 8 Men → 10 days 16 Men → (10 × 8)/16 = 5 days. 16 women → 10 days 8 women → (10 × 16)/8 = 20 days. (16 Men + 8 women)’s work = 1/5 + 1/20 = 1/4 16 Men and 8 women can complete in 4 days. From I & III, 8 Men → 10 days 16 Men → (10 × 8)/16 = 5 days. 5 women → 32 days 8 women → (5 × 32)/8 = 20 days. (16 Men + 8 women)’s work = 1/5 + 1/20 = 1/4 16 Men and 8 women can complete in 4 days. Hence statement I and either II or III is sufficient to answer the question.
