Find the fourth consecutive even number: (I) The sum of the

Poorly worded question. If the question were:

Find the largest of 4 consecutive even numbers of a set X.
(1) The sum of the largest two numbers of the set is 30
(2) The sum of the smallest two numbers of the set is 22

Then the answer would indeed be D.

That's exactly what I thought! i answered B too... but the q says that I'm wrong.
This is the OE.
"From Statement 1, we get the sum of last two of the four consecutive even numbers are 30. (This is an assumption that the only amount of numbers there are is four... That is not stated in the q.)
If x be the last number, the second last number would be x - 2 as the numbers are even and consecutive.
Now, x + x - 2 = 30
or x = 16
Now, if 16 is the last number in the series of even consecutive numbers, the others are 14, 12, and 10.
Thus statement 1 alone is sufficient to answer the question.

Statement 2 gives the sum of the first two numbers as 22.
If x and x + 2 are the first two numbers,
x + x + 2 = 22
and x = 10.
The other numbers in the series are 12, 14 and 16. Thus the question can also be answered using statement 2 alone.

Therefore, both the statements are individually able to answer the question,

Hence (D) is the correct answer."

That's what I thought too...

I concur with Maryea, Bunuel and gmat1220.

With given info: Answer should be "B".

What could be possible scenarios that show statement 1 has multiple solutions?

Example,

One would be assuming only four terms in this sequence to arrive at the same value as statement 2.

Find the fourth consecutive even number:
(I) The sum of the last two numbers is 30
(II) The sum of the first two numbers is 22

Either of the statement is sufficient. If we know even one number we know everything.

If sum of last two numbers is 30 that means that x + x + 2 = 30 hence 2x = 28 and x =14 so the series is 10 12 14 16

Let the consecutive even numbers be x , x+2 , x+4 & x +6
Statement 1. x+4 + x + 6 = 30 This gives, x = 10. Hence, Sufficient.
Statement 2. x + x + 2 = 22. This gives, x = 10. Hence, Sufficient.
