Athletes in Place
Five athletes were returning from a cross-country
race. Athlete C placed third, and athlete E placed
second. From the following information, can you
tell how athletes A, B, and D placed in the race?
Athlete A was not last. Athlete A came in after
E. Athlete D was not first.
Since C was third and E was second, A could only
be first or fourth. Since A was behind E, A could
not be first; therefore A must be fourth. D could
not be first, second, third, or fourth, so D must
be fifth. If D is fifth, A fourth, C third, and
E second, then B must be first.
