D Only III Correct Answer Incorrect Answer
E All of these Correct Answer Incorrect Answer

Solution

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.
