Members of a Guwahati sports club play cricket, football or hockey, as shown. What percentage of these members play all three games?

Members $=17+12+15+10+9+9+8=80$, and 8 play all three: $8÷80=10\%$. 8% reads the count as a percentage, 45% is the share who play at least two $(10+9+9+8)÷80$, and 80% confuses the member count with a percentage.
