Target question: How many of the cans did NOT contain diet soda?
Given: Bob purchased 18 cans of soda
Statement 1: Of the cans Bob purchased, the number containing diet soda is equal to the number not containing diet soda.
So, of the 18 cans of soda, 9 cans contained diet soda, and 9 cans did NOT contain diet soda
Since we can answer the target question with certainty, statement 1 is SUFFICIENT
Statement 2: Of the cans Bob purchased, the number containing diet soda is odd
There are several scenarios that satisfy statement 2. Here are two:
Case a: Bob purchased 3 (odd) cans containing diet soda and 15 cans NOT containing diet soda.
Case b: Bob purchased 5 (odd) cans containing diet soda and 13 cans NOT containing diet soda.
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT
Answer: A
Cheers,

What made me hesitate? I was looking for/asking myself if there was a trick to statement (i) specifically, I wondered if there could be an e.g. that was neither soda nor diet soda which would make information provided in (i) insufficient. This thinking cost me a little time.
