### HideShow timer Statistics

Four men and three women make up a seven-member committee. The committee has one male captain and one female captain. If all seven committee members are seated in a straight row of seven chairs, does at least one man sit next to another man?

(1) No woman sits next to another woman.

(2) The captains sit in the first and seventh chairs.

---------

I thought that the answer is E.

Because (1) could be M W M W M W M but also W M M W M W M

and (2) is insufficient since it could also be either M W M W M W M or for example MMMMWWW.

Where is my fallacy here? Seems like I am overlooking something..

for second statement...both captain sit in first and last chair...but
M W M W M W M===>this you assumed wrong....either one side must be 1 women captain.

hope it helps

see the question is:
does at least one man sit next to another man

according to 2nd statement:
M - - - - - W===>THIS MUCH IS COMPULSORY..
NOW we are left with 5 places....3 men and 2 women....are left....do whatever...there is always a chance that atleast 1 man has to sit next to other...

see..ex...:
M W M W M M W

(1) No woman sits next to another woman.
{M, W, M, W, M, W, M} answer NO.
{M, M, W, M, W, M, W} answer YES.
Not sufficient.

(2) The captains sit in the first and seventh chairs.
{M, X, X, X, X, X, W}
We cannot place 3 remaining M's and 2 remaining W's, so that at least one man does not sit next to another man.
Sufficient.
