33 people {a1, a2, ....a33} meet and shake hands in a circular fashion. In other words, there are totally 33 handshakes involving the pairs, {a1,a2},{a2,a3},....,{a32,a33},{a33,a1}. Then the size of a smallest set of people such that the rest have shaken hands with at least one person in the set is
a. 10 b. 11 c. 16 d. 12

• ans is b , means 11
  here we apply, N/3 so 33/3=11
  we made a set of three people , 1st and 2nd persons meet the shake hands and 3rd one is left.

• as it is in circular fashion the smallest set will consist of 3 people.. because two people can not make that order.so smallest set no is 10.....(10*3)=30 people are divided in 10 groups and rest 3 ..out of which atleast 1 can shake hand.
