Hi,

I think the answer should be B.

Let's take each option and solve the question:
Given Info: no more than half of the members of the board can serve on this subcommittee.

So from option A, we don't know the total number of members in the original committee.
For eg: If the total number of members in the committee is 12 than the condition total number of combinations will be 12C6<900 but if total number of members in the committee is 15 than the total number of combinations will be 15C6>900(here 6 is < half of 15).
Hence option A does not give the answer.

Now, let's take option B,
we are given the initial total number of members in the board committee and we select the maximum number of members for subcommittee i.e. 12/2=6 then the total number of combinations will be 12C6<900. hence this option is sufficient to give the answer.

Hence answer should be option B.

Kindly let me know where I am going wrong.
Thanks in advance.

Hit the kudos if I am right.

12C6 is 924. So 12C6>900.
In this case the answer will always be yes.
So statement 1 is sufficient.
In statement 2:
You can select a maximum of 6 and even a minimum of 2.
Thus insufficient.
IMO A is the answer.

(1) The board decides to select 6 members for the subcommittee.

(2) There are 12 members of the board.




let the total number of board members be x
then according to bylaws
number of members for deciding the CEO \(<=\) x/2 say n

(1) The board decides to select 6 members for the subcommittee.
x can be 12 or 100 or any other number > 12
not sufficient

(2) There are 12 members of the board.
The subcommittee can have 0<n<7 members
total number of combinations can be 6 members + 5 members + 4 members + 3 .....+1 member
If the subcommittee has 6 members = 12C6 = 924 > 900
therefore the number of such combinations will always be > 900

sufficient
B
