There are six students, P, Q, R, S, T and U who have a different number of pens - 2, 4, 5, 7, 9 and 12 (not necessarily in the same order). The number of pens Q has is a prime number. U has 2 more pens than Q. The number of pens R has is a multiple of 4 but not a multiple of 3. P has fewer pens than Q but has more pens than S. Who has the highest number of pens?

3) The number of pens R has is a multiple of 4 but not a multiple of 3.
(So, R has 4 pens only.)

4) P has fewer pens than Q but has more pens than S.
(P cannot have 2 pens as S has fewer pens than P.
So, P has 5 pens and S has 2 pens.)
