Puzzle Test Questions and Answers

Answer: B

E should be immediately followed by C i.e. the order EC should be followed.
D should be immediately followed by B i.e. the order DB should be followed.
One play is staged between A and B and D or E should not be the first or last play.
So, the order is :

B was staged on Wednesday.

Answer: A

Correct answer: M

P is fixed at the third place and S is given the first, so M, N, Q and R fill positions two, four, five and six. M must come before both N and R, and N before Q - that is three companies which must follow M. Only the second place leaves three positions after it, so M must be visited second.

Answer: E

Correct answer: M

The company immediately after P is the fourth. M must precede N and R, and N must precede Q, so three visits have to come after M. With M fourth only two places remain, which is not enough. Every other company can be placed fourth in some valid schedule, so M is the exception.

Answer: D

Correct answer: Fifth

The three visits S, Q, R must be consecutive, and they cannot include the third place, which is reserved for P. The only run of three consecutive places avoiding it is the fourth, fifth and sixth, so S is fourth, Q fifth and R sixth. That leaves M and N for the first two places, in that order since M precedes N.

Answer: A

Correct answer: M, S, P, N, R, Q

Check the three conditions against each option. The third company must be P, which rules out three of the five at once. Of the two beginning correctly, Q, N, P, R, S, M places M last although M must come before N and R. M, S, P, N, R, Q satisfies every condition: P is third, M precedes both N and R, and N precedes Q.

Answer: A

The docotors 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, where there is a male doctor, there will be no female teacher. But three female teachers are selecred. So, C, D and E cannot be selected. Thus, two doctors selected are A and B.
Since female doctors are selected, so male engineers Kand L cannot be selected.
Hence, the team formed is A B O P Q G H

Answer: D

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 docotors 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.

Answer: B

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 docotors 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

Answer: C

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 engineersto 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.

Answer: D

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.
