Answer 2

Hello friend! Thanks for asking question, here is the answer.

>>Let's consider those four people are A, B, C and D.
>> We are not supposed to repeat any hand for shake hands.
>> At the first, A does shake hand with B, C and D. That means THREE shake hands done.
>> Then, B will do shake hand with C and D. That means 2 shake hands done here.
>> After that, C will do shake hand with D. That means only 1 shake hand over here.
>> At last D. No dear friends, D is already with those 3 so here it will be zero
>> According to this, the total number of shake hands without repeating with each other is 6.


I hope this will help you. Thank you.
