Four couples are sitting around a rectangular table along with the host and hostess who are sitting at opposite ends of the smaller side of the table and three people on each on the longer side. Every person had at least one person of the opposite sex next to him/her.
Monish is opposite Savita, who is not the hostess.
Jatin has a woman on his right and is sitting opposite a woman.
Manisha is sitting to the hostess’s right, next to Ishan.
One person is seated between Mamta and Harshita, who is not the hostess.
The men were Monish, Jatin, Ishan and Paras, while the women were Mamta, Harshita, Savita and Manisha.
Q1MULTIPLE CHOICE
Paras must be ...
I. seated opposite Mamta.
II. seated to the right of Savita.
III. seated two places to the right of Manisha.
The host and hostess are sitting opposite to each other on the smaller side of the table.
Manisha is sitting to the hostess’s right, next to Ishan.
Monish is opposite Savita, who is not the hostess. Since each person has at least one person of opposite sex next to him/her, hence, Monish cannot sit between the host and Ishan.
One person is seated between Mamta and Harshita, who is not the hostess. This is only possible when Mamta is the hostess.
Jatin has a woman on his right and is sitting opposite a woman. This is only possible when Jatin sits between Mamta and Harshita and Paras is the host.
Thus, the final arrangement is as shown in the figure above.
Thus, only statements I and II are true.
Hence, option (c).
Q2MULTIPLE CHOICE
If Jatin had exchanged seats with the person four places to his left, which of the following would have been true after the exchange?
I. Neither the host nor the hostess changed seats.
II. One of the longer side of the table consisted entirely of persons of the same sex.
III. No one was seated between two persons of the opposite sex.
Consider the solution to the first question of this set.
Among the pairs given in the answer options, only Monish and Savita are seated opposite each other.
Hence, option (a).
Answer the next 4 questions based on the information given below.
Eight persons – K, L, M, N, O, P, Q and R – are sitting around a circular table facing the centre, but not necessarily in the same order. Each person belongs to a different city among Denmark, Mexico, Australia, Peru, Vietnam, HongKong, Malaysia and Oman. The following information is known about them.
M faces the person who is from Australia.
R faces the person from Oman.
L and P are not from Australia.
M sits third to the right of the person from HongKong.
N sits three places away from the person who is from Denmark.
The persons from Mexico and Peru face each other.
R and O sit adjacent to each other and neither of them sits adjacent to either N or M.
M sits two places away from the person who is from Denmark.
N does not sit adjacent to the person who is from Oman.
The person from Vietnam sits to the immediate left of the person from Peru.
They are sitting in such a way that no two persons whose names start with consecutive letters sit together. For example: L does not sit adjacent to K or M.
M faces the person who is from Australia. M sits third to the right of the person from Hong Kong. The person from Denmark is two places away from M. Hence we get 2 cases.
N sits three places away from the person who is from Denmark. Also people with names starting with consecutive letters do not sit together.
R and O sit adjacent to each other and neither of them sits adjacent to either N or M. L and P are not from Australia and L cannot sit next to M.
The persons from Mexico and Peru face each other. The person from Vietnam sits to the immediate left of the person from Peru.
R faces the person from Oman. This is not possible in case 2. Hence, case 2 is rejected.
From case 1 we get,
Since, P is not from Australia and Q cannot sit adjacent to R hence, K is from Australia.
P cannot sit adjacent to O hence, Q is from Mexico and P is from Oman.
