Is the positive integer n multiple of 24?
1) n is multiple of 4
2) n is multiple of 6

1st insufficient and 2nd is also insufficient, moreover multiple of both may be 12 that's why both together are insufficient. Answer (E)

C is wrong because: you can have the number 12 (that is a multiple of both 4 and 6) and 24 , you can get two answers,, hence wrong. Hope this helps

Its E. n can be 12 and 24. So n can be a multiple of both 4 and 6 and still not be a multiple of 24.
