I looked at the answer key for this question, it says the answer is A, that simply cannot be correct
24. If b is the product of three consecutive positive integers c, c + 1, and c + 2, is b a multiple of 24 ?
(1) b is a multiple of 3,
(2) c is odd.
Answer (A)
Not nescessarily true. Look at 3, 4 and 5. Their product is 60 which is NOT a multiple of 24. What gives?
This question is from section 11 (Data Sufficiency problems) in the ds.zip question pack found on this forum
