Is (3x + 8)/(x + 2) an integer?
(1) x is an integer
(2) x = 0
(1) x is an integer
(2) x = 0
the answer is B.
let's start with the easiest statement.
2. x=0. that means 8/2 = 4 - integer. so statement 1 is sufficient. A, C, E are out right away.
now..statement 1.
x is an integer.
suppose x=1.
3+8=11.
1+2=3.
11/3 = non-integer.
suppose x=0 (satisfies the condition)
8/2 = 4. - integer
since statement 1 can yield two different outcomes, A is insufficient, and we can cross D.
the only answer left is B.

On simplifying we get 3 + 2/(× + 2)
Statement 1
3 plus something ,and this something isn't an integer for all x
Statement 2
When x=0
3+ 2/2=4
So B
