In such type of questions, a few essential criteria for selection of a group of items are given. The candidate has to keep these conditions in mind and make the required selection as per the directions given in each question.

From amongst six days A, B, C, D, E, and F and five girls P, Q, R, S and T, a team of six is to be selected under the following coditions :
(i) A and D have to be together.
(ii) C cannot go with S.
(iii) S and T have to be together.
(iv) B cannot be teamed with E.
(v) D cannot go with P.
(vi) B and R have to be together.
(vii) C and Q have to be together.

If four members have to be girls, the members of the team are :

Option:
A. B C P Q R S
B. B F P R S T
C. B C Q R S T
D. B C P Q R T
Answer: B . B F P R S T

Justification:

In four girls, S and I are taken together. With S, C cannot be there. So, Q will not be there.
If P is included, D and hence A cannot be there.
If R is included, B will be there and hence E cannot be there.
So, only F can be there.
Thus, the team is S T P R B F. So, the answer is (b).
