S11-25 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.
(1) b is a multiple of 3,
(2) c is odd.
statement 1 : gives nothing, if b is a multiple of 3 consecutive integers, it has to be a multiple of 3. Not Suff.
Statement 2 : lets plug values c is odd, we can have 1,2,3 -> not divisible by 24. OR we can have 23,24,25 -> divisible by 24. Not suff
Answer is E
