Find out the number of people who do not play any game?

As given in the Venn diagram, $25$plays cricket, $22$ plays tennis and $16$ plays both.
The number of people who play only cricket is $25 - 16 = 9$
The number of people who play only tennis is $22 - 16 = 6$
So, people who do not play any game are,
$⇒ 40 - ( 6 + 9 + 16 )$
$⇒ 40 - 31$
$⇒ 9$
Hence, option A is the correct answer.
