Answers:

For questions 1 to 5:

From statement one, team would include exactly one among P,
R, S
⇒ P (or) R (or) S.
From statement two, team would include either M, or Q
⇒ M but not Q
(or) Q but not M
From statement three, if a team includes K, it will include
L or vice versa.
⇒ K, L always accompany each other.
From statement four, if one of S, U, W is included, then the
other two also have to be included.
⇒ S, U, W are always together.
From statement five, L and N cannot be included together
⇒ L, N are never together.
From statement six, L and U cannot be included together.
⇒ L, U are never together.
1. 1 From statements one and two; one of P, R, S and one of
M, Q are to be selected. We require one more member.
But from statement three; (K, L) are always together.
Hence ‘L’ cannot be included in a team of 3 members.
2. 3 Again, from statement one; one of P, R, S has to be
selected.
To make a team of ‘5’
‘S’ will be chosen (which leaves out P and R)
⇒ If ‘S’ is chosen ‘U’ and ‘W’ have to be chosen
(statement four)
⇒ If ‘U’ is chosen ‘L’ cannot be chosen (statement five)
⇒ K cannot be chosen (statement three)
And from statement two; one of M (or) Q has to be chosen.
3. 4 From statements one and two
Two members are to be selected.
Of the remaining seven;
To maximize the size of the team.
We would chose S,
⇒ U and W are included in the team (statement four)
We cannot include K (or) L because we would then have to
leave out N and U (from statements five and six)
4. 5 If ‘K’ is included, ‘L’ has to be included (statement
(3))
If ‘L’ is chosen, neither N nor U can be chosen (statements
(5) and (6))
⇒ S, W are also not included because S, U, W have to be
always together. (Statement (4))
Hence one of P (or) R would be selected (statement
(1)) and one of M (or) Q would be selected (statement (2))
 (K, L) and two of the
above five have to be included.
5. 5 If a team includes N, it cannot include ‘L’, and
therefore, not even ‘K’. (from statement five and three)
According to statement (1), one of P or R or S has to be
included.
According to statement (2), one of M or Q has to be selected.
So the following cases are possible
P Q N,
R Q N
P M N,
R M N
If ‘S’ is selected, then S U W M N and S U W Q N are the only
possible cases.

Hence, in all 4 + 2 = 6 teams can be constituted.
