Question

If eight people greet each other at a meeting by shaking hands with one another how many handshakes will take place ?

Answer 1

56 i think but ik its around that area range

Explanation:

Answer 2

28

Explanation:

Let us set each person as a letter:

A, B, C, D, E, F, G, H

Each person will shake hands with 7 people. However, we cannot count a handshake twice, so we need to subtract one:

A = 7

B = 6

C = 5

D = 4

E = 3

F = 2

G = 1

H = 0

Since H is equal to 0, we can take him/her out. Now, we solve:

A + B + C + D + E + F + G = 1 + 2 + 3 + 4 + 5 + 6 + 7

1 + 2 + 3 + 4 + 5 + 6 + 7 = 28

Answer: 28
