(b) A, B, G, H, M, N
c) C, E, K, L, N, R
(d) C, D, K, L, O, P
Ans . D
Solution(12 to 16)
12. The doctors are A, B, C, D and E; female teachers are O, P and Q, engineers are G H, K and L. The three female teachers to be selected are O, P and Q.
Now, wherever there is a male doctor, there will be no female teacher. But three female teachers are selected. So, C, D and E cannot be selected. Thus, two doctors selected are A and B.
Since female doctors are selected, so male engineers K and L cannot be selected. Hence, the team formed is A, B, O, P, Q, G, H.
13. The doctors are A, B, C, D and E; engineers are G, H, K and L; teachers are M, N, O, P, Q and R. Four teachers are needed. There are three male teachers. So, female teachers are also to be selected. So, male doctors i.e. C, D and E cannot be selected. Thus, the two doctors selected will be A and B.
Both the doctors selected are females. So, male engineer K or L cannot be selected and either G or H is to be chosen. Clearly, the impossible team is A, B, K, N, R, P, Q because K is not to be selected.
14. The doctors are A, B, C, D and E; female teachers are O, P and Q; engineers are G, H, K and L. Since two female teachers are to be selected, so male doctors i.e. C, D and E cannot be selected. Thus, the two doctors selected will be A and B. Both the doctors are females. So, male engineer K or L cannot be selected and G and H are to be chosen.
Clearly, the only impossible team is A, B, K, L, P, Q.
15. The doctors are A, B, C, D and E; male engineers are K and L; teachers are M, N, O, P, Q and R. Clearly, the two male engineers to be selected are K and L.
Since male engineers are selected, so female doctors i.e. A and B cannot be selected. Thus, three doctors to be selected are C, D and E. The doctors selected are all males. So, female teachers O, P and Q cannot be selected. Thus, two teachers out of M, N and R are to be selected.
Hence, the possible team is C, D, E, K, L, M, N
16. Since no particular specifications are given, so we shall verify the correctness of the suggested teams separately. Clearly, C, D, K, L, O, P is incorrect because C and D are male doctors and so cannot go with female teachers O and P.
Directions ( 17 to 21 ): Study the information given below and answer the questions that follow:
There are five persons P, Q, R, S and T. One is football player, one is chess player and one is hockey player. P and S are unmarried ladies and do not participate in any game. None of the ladies plays chess or football. There is a married couple in which T is the husband. Q is the brother of R and is neither a chess player nor a hockey player.
Q.17. Who is the football player?
(A) P
(B) Q
(C) R
(D) S
(E) T
Ans . B
Q.18. Who is the hockey player?
(A) P
(B) Q
(C) R
(D) S
(E) T
Ans . C
Q.19. Who is the chess player?
(A) P
(B) Q
(C) R
(D) S
(E) T
Ans . E
Q.20. Who is the wife of T?
(A) P
(B) Q
(C) R
(D) S
(E) None of these
Ans . C
Q.21. The three ladies are:
(A) P, Q, R
(B) Q, R, S
(C) P, Q, S
(D) P, R, S
(E) None of these.
Ans . D
Solution(17 to 21)
Q is neither a hockey player nor a chess player. So, Q must be a football player and thus cannot be a lady. T is a husband (not a lady) and so must be a chess player. Hence, R must be a hockey player, and therefore she must be a lady and T’s wife. So, the information can be summarised as follows:
17.(b): Q is the football player.
18. (c): R is the hockey player.
19. (e): T is the chess player.
20. (c): R is the wife of T.
21. (d): The three ladies are P, R and S.
