Brazilian Grapes

Algebra Level 2

Albert, Beatrice, Charles, Dulce and Edward were still asleep when their mother left a bowl of brazilian grapes with instruction that the grapes are to be divided equally between the 5 children.

Albert woke up first, so he picked up 1/5 of the brazilian grapes and then left. Beatrice woke up next, but thought she was the first to wake up, and therefore took 1/5 of the remaining brazilian grapes and then left. The other three brothers woke up together, realized that Albert and Beatrice had already left, and so equally divided the remaining brazilian grapes between them.

If none of the brothers got more than 20 brazilian grapes, how many brazilian grapes were in the bowl?
