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

56 i think but ik its around that area range

Step-by-step explanation:

28

Step-by-step 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

28

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
