If k, (k+200), (k+350), and 15*K are all multiples of S then S could equal which of the following ?	Choose the correct choice from the following answers
A) 20 B) S=25 C) 75 D) 100 E) 150
{Multiple of S} - {Multiple of S} = {Multiple of S}.   (K+200) - k = 200 = {Multiple of S}.   (K+350) - k = 350 = {Multiple of S}.   Both 200 and 350 are multiples of only option B.   Answer: S=25.
