seats. Betty and Jim don't want to sit next to Alice and
Tom. Alice and Tom don't want to sit next to Gertrude and
Bill. On the otherhand, Sally and Bob don't want to sit next

From the given data, it can be inferred that:
(Sally & Bob) NOT (Betty & Jim) NOT (Alice & Tom) NOT
(Gertrude & Bill)
(A) NOT (B) means A and B can not seat next to each other.
Now, it is obvious that (Betty & Jim) and (Alice & Tom) will
occupy the corner seats as both of them can have only one
neighbour. Therefore,
(Gertrude & Bill) will seat next to (Betty & Jim)
(Sally & Bob) will seat next to (Gertrude & Bill)
(Alice & Tom) will seat next to (Sally & Bob)
Thus, there are two possible arrangements - a mirror images
of each other.
1. (Betty & Jim) - (Gertrude & Bill) - (Sally & Bob) -
(Alice & Tom)
2. (Alice & Tom) - (Sally & Bob) - (Gertrude & Bill) -
(Betty & Jim)

The son of a rich bullion merchant left home on the death of his father. All he had with him was a gold chain that consisted of 138 links. He rented a place in the city center with a shop at the lower level and an apartment at the upper level. He was required to pay every week one link of the gold chain as rent for the place. The landlady told him that she wanted one link of the gold chain at the end of one week, two gold links at the end of two weeks, three gold links at the end of three weeks and so on. The son realized that he had to cut the links of the gold chain to pay the weekly rent. If the son wished to rent the place for 138 weeks, what would be the minimum number of links he would need to cut?
