Question 1014062: If 2800 birds live in a rain forest of 500 square kilometers, then how many birds will be left when half of this rain forest is destroyed by logging? Answer by ikleyn(52914) (Show Source):
Usually the problems of that kind are accompanied by explanations, saying
. . . bla - bla - bla . . . the bird population is proportional to the forest area.
Then the question makes sense and can be resolved.
Without such explanations the question does not make sense.
