Directions (Q5-9): Read the following information carefully and answer the questions given below it:-
K,L,M,N,O,P,Q,R,S,U and W are only ten members in a department. There is a proposal to form a team from with in the members of the department, subject to the following conditions.
· A team must include exactly one among P,Q and S· A team must include either M or Q , but not both· If a team includes K, then it must also include L, and vice versa.· If a team includes on among S,U and W, then it must also include the other two· L and N cannot be members of the same team· L and U cannot be members of the same team?
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 TeamOptions (5) : P,Q and N is a possible team.
who can be a member of a team size 5 ?
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 ROption (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)
what would be the size of a team includes K ?
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
what would be the size of the largest possible team ?
To have the largest possible team we should include S , U and W.
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.
In how many ways a team can be constituted so that the team includes N ?
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.
