If {p} denote the remainder when 3p is divided by 2 then which of the following is equal to 1 for all positive integers p?
I. {2p+1}
II. {2p}+1
III. 2{p+1}	Choose the correct choice from the following answers
A) I only B) II only C) I and II D) III only E) II and III
I and II - I and II   3p/2 = 0 or 1   I just substituted 1 in the equations and solved.
