Suppose that in the Baltimore metro area, 25% of the crimes [#permalink]  16 Oct 2005, 04:32
Suppose that in the Baltimore metro area, 25% of the crimes occur during the day and 80% of the crimes occur in the city. If only 10% of the crimes occur outside the city during the day, what percent occur outside the city during the night?

A 10%
B 12%
C 20%
D 22%
E Not enough information provided

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.
