(iv) If C is selected then E should also be selected while F should be rejected.
Q. If team size is 3 then which one of the following can not be a part of the team?
Lets consider the different cases here
Case (i): Teams with 2 members:
A cannot be a member of any such team as otherwise at least one of B and C must be selected ( From condition (ii) and if B is selected then D also and if C is selected then E also hence in this case number of teams would be more than Possible teams are:
(B, D), (C, E), (D, E ) and (E, F)
Case (ii): Teams with 3 members: Possible teams with 3 members are (A, C, E), (A, B, D), (C, E, D)
Case (iii): Teams with 4 members: Possible teams with 4 members are (A, B, D, F), (A, C, E, D)

This is the above largest possible team with 5 members.
Direction: K, L, M, N, P, Q, R, S, U and W are the only ten members in a department. There is a proposal to form a team from within the members of the department, subject to the following conditions:
(i) A team must include exactly one among P, R and S.
(ii) A team must include either M or Q but not both.

(vi) The size of a team is defined as the number of members in the team.
Q. In how many ways a team can be constituted so that the team includes N?
Given in the question ,
If the team includes N, then it does not include L and K.
One out of M and Q can be include and one out of P,S and R can be included. If S is a member, so are U and W will also be member.
So we can select one out of M and Q in 2 ways
And we can select one out of P, S and R in 3 ways
Hence total number of ways = 2 x 3 = 6 ways.
