Answer 2

Answer:

435

Step-by-step explanation:

the total no. of leaders=30

that means...every person shook 29 hands

i.e. 30x29=870handshakes

but for every handshake two poeple are involved..therefore 870 is the double count for the same

therefore half of the handshakes=870/2

therefore the total handshakes are 435
