SOLUTION

Committee member W wants to schedule a one-hour meeting on Thursday for himself and three other committee members, X, Y, and Z. Is there a one-hour period on Thursday that is open for all four members?

(1) On Thursday W and X have an open period from 9:00 a.m. to 12:00 noon. No information about Y and Z. Not sufficient.

(2) On Thursday Y has an open period from 10:00 a.m. to 1:00 p.m. and Z has an open period from 8:00 a.m. to 11:00 a.m. No information about W and X. Not sufficient.

(1)+(2) From above we know that all four members have an open one-hour period from 10:00 a.m. to 11:00 a.m. Sufficient.

Answer: C.

I believe C is the right answer.

Statements 1 & 2 together tells us that W, X, Y and Z all have a one-hour open period on Thursday from 10am to 11am.

Waiting for the OA.

1) On Thursday W and X have an open period from 9:00 a.m. to 12:00 noon.
(2) On Thursday Y has an open period from 10:00 a.m. to 1:00 p.m. and Z has an open period from 8:00 a.m. to 11:00 a.m.

statement 1 : W and X: 9 to 10, 10 to 11 , 11 to 12
statement 2:y : 10 to 11 , 11 to 12, 12 to 1
Z:8 to 9, 9 to 10, 10 to11

1+2 gives a common slot of 10 to 11

hence C
