A triangle whose side lengths are whole numbers has one side which measures 25 inches and a perimeter of 80 inches. What is the fewest number of inches that can be the length of one of the remaining sides?

16.

 

you know that in triangle abc, a+b is more than c, c-b < a, and from there you can get that the largest possible side is 39, yielding 16 as the smallest.
