Exactly seven persons- J,K,L,M,N,O and P participate in and finish all of a series of 1km races. There are no ties for any position at the finish of any of the races. 1). P always finishes somewhere ahead of J. 2). J always finishes somewhere ahead of K. 3). Either L finishes first and N finishes last, or M finishes first and O or K finishes last.
Q. No. 1:
If in a race M finishes sixth and K finishes fifth, which of the following can be true ?
Answer: C I). P > J II). J > K => P > J >K III). Either L = 1st and N= 7th or M = 1st and O/K = 7th. If M = 6th and K =5th, then we get L, O/P, J/P/O, J/O, K,M,N. Hence only option C satisfies the condition.
Q. No. 2:
If in a race M finishes second, which of the following can be true ?
Answer: A I). P > J
II). J > K => P > J >K
III). Either L = 1st and N= 7th or M = 1st and O/K = 7th. If M = 2nd, then we get L, M, O/P, J/P, K/J, O/K, N Only option A satisfy the condition.
Q. No. 3:
If in a race L finishes second and K finishes fifth, which of the following must be true ?
Answer: C I). P > J
II). J > K => P > J >K
III). Either L = 1st and N= 7th or M = 1st and O/K = 7th. If L = 2nd and K = 5th, then we get. M,L,P,J,K,N,O
Q. No. 4:
If in a race L finishes first, P can finish no lower than
Answer: D I). P > J
II). J > K => P > J >K
III). Either L = 1st and N= 7th or M = 1st and O/K = 7th. According to the question, we see that L _ , _ , P, J,K,N
Q. No. 5:
If in a race P finishes fifth, which of the following must be true ?
Answer: D I). P > J
II). J > K => P > J >K
III). Either L = 1st and N= 7th or M = 1st and O/K = 7th. If P =5th then, M .....PJK We see that if K =7th, then M must be 1st.

An operating room scheduled is being set up for Monday and Tuesday of a certain week. On each of the days, either, one long and two short operations or else four short operations must be scheduled. For each operation, a surgeon- Charu ; Sharma or Tendulkar- will be scheduled. Patients are scheduled will be selected from among patients 1,2,3,4,5,6,7,8 and 9. The following will be met. 1).

The operations for patients 1 and 3 will be long and the operations for other patients will be short. Patient i must be operated on by Dr. Tendulkar, patient 2 and 4 by Dr. Sharma and patient 7 and 8 by Dr. Charu.
Q. No. 1:
Which of the following could be the schedule of patients from the first to the last patients to be operated on during the two days ?
Answer: A Tendulkar performs the long operations on 1, hence he cannot be selected on Monday.

A psychologist has designed an experiment that involves running for five mice - C,D,E,F and G through a maze that is connected to five compartments 1,2,3,4 and 5. The experiments places each muse in one of the five compartments. When a bell is rung, each muse leaves its compartments, runs through the maze, and enters or reenters one of the five compartments. At no point is there more than one mouse in one compartment. 1). When the bell rung, any mouse placed in 4 always goes to 2, and any mouse placed in 2 always goes to 4. 2). When the bell rung, any muse placed in 5 always goes to 3, and any mouse placed in 3 always goes to 5. The experimenter has designed the experiment such that after the mice have run through the maze, the following outcome always obtained. i). G is neither in 3 nor in 4. ii). If E is in 1, F is in 2. iii). If G is in 2, F is in 5.
Q. No. 1:
If C is in 5 after mice have run through the maze, G must have been in which of the following before running through the maze ?
Answer: A On the basis of information and conditions we know that G cannot be in 2nd and 5th compartment before running, because after running G neither in 3 nor 4. Again, if C is in 5 after running that means C is in 3 before running. So, only option A is left from the given option.
Q. No. 2:
If G is in 2 after the mice have run through the maze, F must have been in which of the following before running through the maze ?
Answer: C If G is in 2 after running this means F is in 5 after running and this means F must be in 3 before running because 5 and 3 interchanged after running.
Q. No. 3:
Which of the following is a possible distribution of the mice after they have run through the maze ?
Answer: B Option A and C are replaced due to position of G. Option D is wrong because G is in 2 then F must be in 5 and here F is not in 5.

If HB is chosen, SR cannot be chosen. 5). If only TW, then either SR or AC or both is required. If a buyer does not want AC but wants the maximum number of options, then he will have to leave HB. Because HB or SR only one can be chosen. If HB is taken then you cannot take TW and If SR is taken then you can take TW also and hence, this will be more options.
Q. No. 2:
Which of the following options can be chosen without the purchase of additional options?

Answer: D 1). If AC is chosen, then HDE, HDS and TW are also required.
2). If PB/PS/PW is/are chosen, then HDE is also required.
3). If HDE is chosen, then PB is also required
4). If HB is chosen, SR cannot be chosen.
5). If only TW, then either SR or AC or both is required. If Ac is to be taken then as per the conditions HDE, HDS and TW are also required and if HDE is taken then you must take PB also. Thus, D option is absolutely fulfill the conditions. Others are invalid.

Answer: B If B and L are assigned to van 1 then E must also be assigned to van 1. This means other 3 are assigned to van 3 and C alone is assigned to van 2.
Q. No. 6:
If E is the only paramedics not yet assigned, and if; at this point, E could be assigned to anyone of three vans, which of the following must be TRUE ?
Answer: A As E could be assigned to any van, this means B should not be assigned to van 1. As in the van 2, C is already there and one place is to be blank for E. Since L cannot be assigned to van 3, therefore, L must be assigned to van 1.
