when we consider the 1st statement .,we cannot judge as we dont know the number of tollbooths..
When we consider the 2nd statement alone...we dont know the distance between the tollbooths even we know the number of booths...
When we consider both the statements ... we know that the 1st and 2nd booth are 25miles apart even if we distribute 4 booths in between 25miles there should be any 2 booths that have a distance less than 10miles...
So i think the answer should be C
