in a jungle there are $$p$$ banana trees.each tree has $$q$$ bananas.$$r$$ monkeys live in the forest.
in how many ways can the monkeys eat the bananas so that at least 1 banana is eaten from each tree and each monkey eats at least 1 banana. :P

hahahah. Nice problem. But, why convert the problem in banana? It was better in mosquito. Lol. Please write down the mosquito problem also in here :) :P

Can I ask you people just one thing? What is the source of the problem? Please be honest.
