In how many days will 5 men complete a work? (I) 2 women, 5 men and 3 children complete a work in 8 days. (II) 6 women can complete the same work in 16 days.

  1. If statement I alone is sufficient but statement II alone is not sufficient.

  2. If statement II alone is sufficient but statement I alone is not sufficient.

  3. If each statement alone (either I or II) is sufficient.

  4. If statement I and II together are not sufficient.

  5. If both statement together are sufficient, but neither statement alone is sufficient.

D Correct answer
Explanation

Statement I: 2W + 5M + 3C = 1/8 of work per day. This has three unknowns (W,M,C work rates). Statement II: 6W = 1/16 of work per day, so W = 1/96. But we still need M and C's individual rates or their relationship. Even combining both, we have 2 equations with 3 unknowns (M, C, and total work). The statements together are insufficient.
