Hello all

I have another percentages question that I think that you could help me with as it looks fairly basic but I am having trouble understanding the logic behind it.

Q. What percentage of total eligible adults in the 18–24 age category turned out to vote in Thundersley?

a) 3.8% b) 6% c) 9.5% d) 12.8% e) 15%

All the information is below in the table.

Any help would be great.

Cheers!
