It will be seven if they shake with one hand each but fourteen if they shake with two hands each.
It will be 14 handshakes

7 hand shakes but both hands is 14 hand shakes
This is simply 7C2 which is 7!÷{2!(7-2)!}
Which equals 21
7 people met and each shake hands with each other… That means each person would shake 6 people that is 6*7=42 handshakes
