A, P and U have to be together.

B cannot go with D or R.

E and Q have to be together.

C and T have to be together.

D and P cannot go together.

C cannot go with Q.

If the team is to consist of one advocate, three docotors and one male teacher, the members of the team are

• A. A D P S U
• B. C D R S T
• C. D E Q R S
• D. D E Q R T

Answer 1

The correct option is C D E Q R S

The advocates are A, B and R;

The doctors are C, D, P, Q and S;

Male teacher is E.

Clearly, E will be selected, E and Q have to be together. C and Q cannot be together.

So, C will not be selected. P also cannot be selected because U is not selected.

So, two other doctors D and S will be selected.

P is not selected, so A will not be selected.

D is selected, so B cannot be selected.

Thus, the team is D E Q R S.
