The local grocer is a would-be mathematician.  He likes to arrange his apples in nice rows.  However, when he lays his apples in rows of 3 he has one left over.  When he lays them in rows of 5 he also has one left over. Remarkably he also has one left over when he arranges them in rows of 7 and 9. 11 seems to be the magic number, for, in rows of 11 there are no apples left over.  How many apples does the grocer have?
