What fraction of the cookies in a certain bakery’s window display contains nuts?
To solve this we need the percentage of cookies containing nuts or not containing nuts.
Statement (1) Of the cookies in the display, 22 contain nuts.
This statement does not give any information on the total number of cookies. Just having the number of cookies containing nuts is not helpful. Hence this statement is not sufficient.
Statement (2) Of the cookies in the display, 90% do not contain nuts.
This statement clearly tells us percentage of cookies not containing nuts, from which we can easily calculate the percentage of cookies containing nuts. Hence this statement is sufficient.
Answer is B

Target question: What fraction of the cookies in the display contains nuts?
Statement 1: Of the cookies in the display, 22 contain nuts.
We have no information about the number of cookies WITHOUT nuts.
So, statement 1 is NOT SUFFICIENT
If you're not convinced, let's consider two possible cases:
Case a: There are 22 cookies WITH nuts and 8 cookies WITHOUT nuts. So, there are 30 cookies in total, and 22 have nuts. In this case, the answer to the target question is 22/30 of the cookies have nuts
Case b: There are 22 cookies WITH nuts and 2 cookies WITHOUT nuts. So, there are 24 cookies in total, and 22 have nuts. In this case, the answer to the target question is 22/24 of the cookies have nuts
Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: Of the cookies in the display, 90% do not contain nuts
If 90% DON'T have nuts, then 10% DO have nuts.
10% = 10/100 = 1/10
The answer to the target question is 1/10 of the cookies have nuts
Since we can answer the target question with certainty, statement 2 is SUFFICIENT
Answer: B
