Answer is B.

Total birds = 450 = 5 * Other Anilmals (X)

or X = 90.

So, Difference in Birds and X = 450-90 = 360.

ANSWER: B If the 450 birds are 5 times the number of non-bird animals, then non-birds=450/5=90. 450-90=360 more birds than non-birds at the zoo.

I know I am getting it wrong but this is how I interpreted the question:

Birds : Non Birds
5x : x
So the overall is 6x =450
x= 75

Question is asking us to find 5x-x ----> 4x =4 * 75 = 300 (which is not in the answer choices ;) )

We are given Total birds = 450 , not total animals.

So, it should be 5x=450 or x=90.

The highlighted portion above is incorrect.
