Rephrase:Positive integers a, b, c, m, n, and p are defined as follows: m = 2^a * 3^b, n = 2^c, and p = 2m/n. Is p odd?
(1) a < b
(2) a < c
P = (2 * 2^a * 3^b)/2^c; hence we need to find whether c = a + 1
Stmt 2 states that c > a. With this we can be sure that P is not even. If c is 4, and a is 2, p will not be an integer. If c is 3 and a is 2, then p must be odd.
IMO B
