Example from OG:
In a certain production lot, 40 percent of the toys are red and the remaining toys are green. Half of toys are small and half are large. If 10 percent of the toys are red and small, and 40 toys are green and large, how many of the toys are red and large?
On the given information it is easy to compute that there is 30% toys that are large and red. But what I don't understand is how can I know n - number of the toys n=200 (if the only number in task is 40 toys)?
