In a room there are N number of people if everyone shakes hands how many handshakes are made?

Depends what you mean, if you mean if everyone shakes hands just once then N-1 handshakes are made. If you mean if everyone shakes hands with everyone else then the answer is (N-1)+(N-2)+....+2+1 (we dont include N as they're not going to shake their own hand, obviously) written as Σn-1i=1 i, this is a arithmetic progression and so the total number of handshakes will be equal to (1+(n-1))(n-1)/2

Prove that total number of people who lived on earth and made odd number of handshakes is always even?

If you multiply anything by 2 it always comes out even. So if people make 35 handshakes, we multiply it by 2 and we get 70 people. This will work with any different number of handshakes, odd or even.

How many people are there if everyone shakes hands and there are 66 handshakes?

Assuming that each person shakes hands with every other person, there are 12 people. Let n be the number of people. Then each person shakes hands with (n-1) people and if you ask every person how many hand shakes they made and total them you will get a total of n(n-1) handshakes. However, each handshake involves two people and has been counted twice - once by each person that shook hands - thus number of hand shakes is half of this, giving: n(n-1)/2 = 66 ⇒ n(n-1) = 132 ⇒ n2 - n - 132 = 0 ⇒ (n - 12)(n + 11) = 0 ⇒ n = 12 or -11 You can't have -11 people, therefore there are 12 people.

When would you not shake hands?

* If a person does not extend their hand to be shaken then don't shake their hand. If you are making a deal in business or if you have made up with a friend (especially males) then you can extend your hand to be shaken. Shaking hands is to seal a deal of good faith in all areas of society.


If 7 girls shake hands only once how many handshakes does that make?

The question is ambiguous:If each girl shakes one other person's hand once, then there are seven (7) handshakes.If each girl shakes each other girl's hand once, then there are 7 x 6 x 0.5 = 21 handshakes (each girl x each other girl x cancelling out the doubles).Another way to look at this one:If each girl shakes each of the other girl's hand once, there would be 42 shakes (each girl shakes 6 hands, times 7 girls, an assupmtion is made that each girl is not shaking her own hands, you can't tell much from the question so assuming ensues)
