Hi All,
In these types of prompts, it's certainly helpful if you know your Number Property Rules (in this case, the rules of division). Even if you didn't know those rules those, you could solve with algebra and a bit more work.
We're told that there are 3 CONSECUTIVE EVEN integers. We can call those integers:
X
X + 2
X + 4
The sum of those integers = 3X + 6
From here, you can check all five answers. The correct answer will leave you with an EVEN INTEGER value for X... And at this point you might more easily recognize the "rule of 3" for division....
Answer A: 3X + 6 = 200 --> 3X = 194 194 is NOT a multiple of 3. Eliminate A.
Answer B: 3X + 6 = 303 --> 3X =297 X = 99 which is NOT an even integer. Eliminate B.
Answer C: 3X + 6 = 400 --> 3X = 394 394 is NOT a multiple of 3. Eliminate C.
Answer D: 3X + 6 = 554 --> 3X = 548 548 is NOT a multiple of 3. Eliminate D.
Answer E: 3X + 6 = 570 --> 3X = 564 X = 188 which IS an even integer.
Final Answer:
GMAT assassins aren't born, they're made,
Rich
