50 students of a certain class took a test. How many of them got a score less than 82?E
1). the average score is 82
2). the median is 82
Statement 1: Clearly INSUFF.
Statement 2: If the 25th and 26th scores are both 82, then there are 24 scores less than 82.
If they are different (say, 25th is 81 and 26th is 83), then there are 25 scores less than 82. INSUFF
Together, knowing the average doesn't help. INSUFF
In this question I immediately thought of the mean equal the median, consecutive numbers. so you'll have consecutive numbers leading ie. .....79,80,81,82,82,83,84,85.... why is that line of thought incorrect?
