One week a truck rental company had a total of 20 trucks, [#permalink]  10 Dec 2005, 19:38
One week a truck rental company had a total of 20 trucks, all of which were on the lot Monday morning. If 50 percent of the trucks that were rent out during the week were returned to the lot on or before Sat morning of that week, and if there were at least 12 trucks on the lot that Sat morning, what is the greatest number of different trucks that could have been rented out during the week?
