4 quarters of x is 36. X is equal to
A)9
B)50
C)144
D)40

4 quarters of something implies 4/4 which is 1. therefore X=1

The only possible choice assumes a typo where you meant to say that one quarter of x is 36.
Then, x is 144.
Hmm. Unless the question reads
4 quarters of x is 36. What is 1 quarter of x?
Then the answer is 9.
