TT GWD 8-36 ?

Q36:

If n is an integer and 100 < n <200, what is the value of n?

(1)   n/36 is an odd integer.

(2)   n/45 is an even integer.

                  

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

Key is B, but my answer is C. Any clue why B is correct? Thanks.
