For me (B) :)

Stat 1
o If n/36 = 3, then n = 108
o If n/36 = 5, then n = 180

INSUFF.

Stat 2
There is only n/45 = 4 (n = 180) that matches.

SUFF.

The source is a set of 'tough' quant questions that I got from a friend. He got it from the Kaplan classes that he attended. Hmm...doesn't speak to well about the quality of their tutoring, does it?! :wink:

I guess most of those independent tutoring services give a question with a mistake answer once in a while...

And yes, it´s B.

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.

From Statement 1:

n/36 to be an odd integer first multiple 36 * 5 (approx) and you will get 180 which means that 36*6 will give you a number beyond 200. The previous odd integer is 3 (36*3 = 108) which is in between 100 and 200.

2 values of n = 3 and 5. Cannot determine a single value for n (INSUFF)

Therefore BCE

From Statement 2. To get an even integer multiply 45 by 4 and 2

45*4 = 180 which seems to be the highest number divisible by 45 in that range of 100 and 200.

45 * 2 = 90 is a number out of the range of 100 and 200.

Bingo... One value of 4 for n between 100 and 200. B is the BEST CHOICE
