Question

There are $11$ players in Indian team who won 20-20 world cup in 2007. If each player shakes hands with all players, how many hands are shaken?

• A. $50$
• B. $110$
• C. $55$
• D. $60$

Answer 1

The correct option is C $55$

Since there are 11 players

So the number of hands shaken by 1 person=10

similarly no. of hands shaken by 2 person=9

..Similarly, the last person shakes hand with only itself

Total number of hand shaken=$\frac{10\times 11}{2}=55$
