(1) 2 (2) 3 (3) 4 (4) 5 (5) 6

Answers & Explanation:

1) Ans – 1

Explanation: If L is in the team K will also be in the same Team. Exactly one among the P,R and S and exactly one among the M and Q are included in the team. hence when L is in the team , the team strength will be atleast four. Hence L cannot be in the team of three.

Options (2) ,(3) and (4) : M,P and N is a Possible Team

Options (5) : P,Q and N is a possible team.

2) Ans – 3

Explanation: Options (1) and (2) : If K is in the team , then L is laso included and vice versa.

ð Neither U nor N is included.

When U is not included neither S nor W is included.

From (ii) , only one among M and Q is included.

From (i) Only one among P and R is included.

Hence , the team can be K L M P or K L M R or K L Q P or K L Q R

Option (3) :If M is included , then q cannot be included. If S is included then both U and W are included.

Hence , the team is M , S , U , W and N.

Option (4) and (5) : If any one of P or R is included then S cannot be included.

ð U and W are also not included.

Only one among M and Q is included.

If K is included , then L is also included.

ð N cannot be included.

ð Hence , the team can be (P,M or Q) , (K,L or R) ( K,L and M or Q)

3) Ans – 4

Explanation: To have the largest possible team we should include S , U and W.

ð Neither P nor R is included.

Only one among M and Q is included.

Both K and L can included.

Since , L is included neither N nor U can be included.

Hence , the maximum possible strength of the team is 5.

4) Ans – 5

If K is included , then L is also included.

ð Both N and U are not included.

Since U is not included neither of s and W is included.

ð The term consists of only four members.

5) Ans – 5

If N is included , then L is not included.

ð K is not included.

But U may or may not be included.

Case (i): U is included.

ð S and W are also included.

ð Neither P nor R is included.

One among N nor R is included.

Hence , the possible teams are N , U , S , W and P or N , U , S , W and Q.

Case (iI): U is Not included.

ð S and W is included.

ð Exactly One Among P and R is included.

Exactly One among M and Q is included.

Hence , the possible teams are (N , P and M ) or ( N, P and Q ) or ( N ,R and M) or ( N , R and Q )

Hence the teams can be formed six different ways.
