Q. A group of people is sitting around a round table. They give a coffee break. When they return to the table after the break, they sit down randomly. Interestingly, they notice that the six closest persons sitting next to each one of them (three to the left, and three to the right) are completely different from the six closest persons in the previous setting.

At least how many persons should be there?

@ chaitanya and others,
pls check.
As per your solution 17 persons are required and arrangement is given as
1,5,9,13,17,4,8,12,16,3,7,11,15,2,6,10,14

1,14,10,6,2,15,11,7,3,16,12,8,4,17,13,9,5
pls see that in second arrangement, 10 is surrounded by same persons like 1,14 on one side and 6,2 on other side where as
statement says

the six closest persons sitting next to each one of them (three to the left, and three to the right) are completely different from the six closest persons in the previous setting.

any justifications ??????

The answer is 5 turns.First we consider first 4 nos,then we assume the friend has thought of the other 5.so he loses a turn.So next two turns will be wasted in the same way.Next 2 turns,he guesses numbers this way..1,2,3,5..so if 5 is among the guessed numbers,.1 turn is successful...next two turns he guesses the next two.
