If A and B are positive integers, A - 4 is divisible by 4 and B - 2 is divisible by 2, all of the following could be the value of A - B Except? Choose the most appropriate option
A) 4
B) 8
C) 10
D) 14
E) 3
A-4 = 4B   =&gt; A = 4B + 4 = 4,8,12,16,20,24,28,32,36   B-2 = 2A   =&gt; B = 2A + 2 = 2,4,6,8,10,12,14,16,18,20   4 = 8 - 4   8 = 12 - 4   10 = 16 - 6   14 = 32 - 18   So , we can see that all the answer choices are possible here except 3
