If A is an even integer and q is an odd integer, which of the following must be an odd integer?
Choose the correct option:
A) A/q B) Aq C) 2A+q D) 2(A+q) E) 3A/q
this is a must question:   A. A/q   can be a non-integer   B. Aq   always even   C. 2A+q   2A = even -&gt; even+odd = odd   D. 2(A+q)   always even - A+q = odd *2 -&gt; even   E. 3A/q   might be a non integer.   2A+q
