From I, In statement I there is only one condition. So we cannot find the answer. From II, We have to find the days of men’s work and in statement II, the data is regarding women. So we cannot find the answer. From III, 3 men = 16 days ∴ 8 men = (16 × 3)/8 = 6 days Hence, only statement III is sufficient to answer the question.
