Question 103

Let $p(x)$ be a polynomial with integer coefficients such that $p(0)=6$. It is known that among the integers $m$ between 1 and 60 exactly 40 are such that $p(m)$ is a multiple of 3; moreover, it is known that among the integers $m$ between 1 and 60 exactly 30 are such that $p(m)$ is a multiple of 4. How many are the integers $m$ between 1 and 60 such that $p(m)$ is a multiple of 6? Note: all the intervals appearing in this problem are to be considered with their endpoints included.
(A) 10
(B) 20
(C) 25
(D) 30
(E) 40
