Hola!
It is kinda Brain Teaser... let's try to find out the answer :)

ATQ,

→ The first person shakes hands with all 49 others.

→ The SECOND person only has to shake hands with 48 others, as he’s already shaken hands with the first person.

→ The third person shakes hands with seven others.

n' the cycle continues till it REACHES the last person!

Applying logic :

49 + 48 + 47 + ... + 1 = 1225

Hence,
In total 1225 hands were shaken in the party.

Hope it helps! :D
