1) not sufficient. Unless the questions says how many total consecutive integers are 1) is NOT sufficient.
2) is sufficient. lets say numbers are n, n+2
2n + 2 = 22
n = 10
so first two numbers are 10,12. Hence we can find the fourth consecutive even. Sufficient.
Unless the questions says how many total consecutive integers are 1) is NOT sufficient. hence B
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."
Thank you for your kudoses Everyone!!!
