Alison, the company CEO, wants to schedule a one-hour meeting on Monday for herself and three other managers, Bob, Colleen, and David. Is there a one-hour period on Monday available to all four people?

(1) On Monday, Bob has an open period from 12:00 p.m. to 3:00 p.m. and David has an open period from 2:00 p.m. to 5:00 p.m.
(2) On Monday, Alison and Colleen have an open period from 11:00 a.m. to 3:00 p.m.

Kudos for a correct solution.

OFFICIAL SOLUTION:

This data sufficiency problem doesn’t require much math skill. You just have to try to synchronize schedules.

Statement (1) tells you about Bob and David’s schedules (they can meet from 2:00–3:00) but tells you nothing about Alison and Colleen. Statement (1) isn’t sufficient, so you can eliminate A and D.

Statement (2) tells you about Alison and Colleen’s schedules (they can meet between 11:00 and 3:00), but it doesn’t mention Bob and David. Statement (2) isn’t sufficient, but you’ve probably already figured out that because statement (1) gives you Bob and David’s times and statement (2) gives you Alison and Colleen’s times, the two statements together can answer the question. Eliminate B and E. C is the correct answer.

Hi Bunuel, lets say, if we couldn't derive at the free slot from the given info(combining both stmt 1&2), should we just assume that there is no other slot available in the repective people's schedule and mark answer C [soln being no slot available] or should the answer be E [ since we do not have info on the rest of the day's schedule of different people].
