a jar of 264 marbles is divided equally among a group of marble - players . if 2 people join the group , each one would receive 1 marble less . how many people are there in the group today ?
"only 22 and 24 divide 264 perfectly , assume initially , there are 22 people , , each will get 12 marbles two people join , then 24 will get 11 marble each . hence answer e = 24"
divide(subtract(sqrt(add(multiply(multiply(264, 2), const_4), power(2, 2))), 2), 2)
