Choice E: Data insufficient
Question stem: N consecutive integers. So, they are all distinct numbers. Median is 24.
Statement 1: Smallest of these N integers is greater than 21.
There will be as many integers less than 24 as there are more than 24. And smallest number should be at least 22.
Possibility 1: The set is {22, 23, 24 25, 26}. The largest of these N integers is 26.
Possibility 2: The set is {23, 24, 25}. The largest of these N integers is 25.
Possibility 3: The set contains just 1 element. {24}. The largest of these N integers is 24.
More than one possibility. Statement 1 alone is NOT sufficient.
Statement 2: N is odd.
N could be 1. In which case, the largest integer is 24.
N could be 3. In which case, the largest integer is 25.
We cannot determine a unique value for the largest of these N integers from statement 2.
So, statement 2 alone is NOT sufficient.
Combining the 2 statements: We narrowed down the set to 3 possibilities using statement 1.
In all the 3 possibilities N was odd. So, all 3 sets are likely contenders.
So, we cannot find a unique value for the largest number.
Statements together NOT sufficient. Choice E.
