v, w, x, y, and z are five positive integers for which v≤w≤x≤y≤z. If the average (arithmetic mean) of the five numbers is 30 and their median is 25, which is the smallest possible value of z? Choose the most appropriate option
A) 30
B) 35
C) 37
D) 38
E) 40
sum=150   mid value = 25   minimize 'z'. So, 25 25 25 37 38   answer: 38
