The amount is on the page that the individual minion is on. EX: http://leagueoflegends.wikia.com/wiki/Caster_Minion

The side bar thing says: "Experience:  29.44 (+2.76 / 3 min)"

And I would asume it would divide the exp based on the number of champions in range. EX: 1 champ get 100%, 2 champs get 50%, ect.
