Seems like a trick problem. Let 100= total number of crimes committed.

20 occur outside the city, (100*.20). Half occur during the day (10) so the other half must occur during the night (20-10=10).

The answer is 10%. This problem is easily solved by drawing a table and using 100 as a trial value since we're dealing with percentages. Please see my attachement for the solution.
