Ex 8. If the team is to consist of one advocate, two doctors, three teachers and C may not go with T, the members of the team are :

(A) A E P Q S U (B) A E P Q T U (C) B E Q S T U (D) E Q R S T U Sol. (B) The advocates are A, B and R ; doctors are

C, D, P, Q, S ; teachers are E, T and U. The team consists of 3 teachers i.e. E, T, U. Now, A, P and U have to be together. E and Q have to be together.

Thus, the team is A E P Q T U.

Ex 9. If the team is to consist of one male advocate, one male doctor, one lady doctor and two teachers, the members of the team are :

(A) A C P T U (B) A D E P T (C) A D E P U (D) B C E Q U

Sol. (A) The male advocates are A and B ; male doctors are C and D ; lady doctors are P, Q and S ; teachers are E, T and U. If A is selected, P and U will be selected. D and P cannot go together. So, a male doctor C will be selected. C and T have to be together. Thus, the team is A C P T U. If B is selected, D will not be selected. So, male doctor C will be chosen. C and T have to be together. Now, the second teacher to be selected is E or U. But, U cannot go without A. So, E will be selected. E and Q have to be together. Thus, the team can also be B C E Q T.

Ex 10. If the team is to consist of one advocate, three doctors 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

Sol. (C) 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.

Ex 11. If the team is to consist of two advocates, two doctors, two teachers and not more than three ladies, the members of the team are :

(A) A B C P T U (B) A C P R T U (C) A E P Q R T (D) B C E Q R T Sol. (A) A C P R T U and A E P Q R T are wrong because

each of these combinations consists of four ladies.

B C E Q R T is incorrect because B and R cannot go together.
