    B and D have to be together.
    C cannot go with Q.
    F cannot go with A or D.
    P and R have to be together.
    P cannot go with S.
    A and E have to be together.
    Unless otherwise mentioned, the above criteria are applicable to all the following questions:
    If at least three members have to be girls and C agrees to team with Q but Q refuses to team with A. then the team consists of

    A)  B,C,D,P,R,S       

    B)         B,D,E,P,Q,S

    C)  B,C,D,P,Q,R      

    D)         A,C,E,P,R,S

    Correct Answer: C

    Solution :

     At least three girls out of P, Q, R and S must be selected. But, P cannot go with S. So, either P, Q, R or Q, R, S must be selected. But, P and R have to be together. So, P, Q, R must be selected. If Q is selected, A and hence E must not be selected. Since C agrees to team with Q, so C must be selected. B and D have to be together. So, the remaining two boys selected must be B and D.
