A) If n is a positive multiple of 4 it should be of the form 4*x where x is 1, 2, 3,4 etc therefore, n can be 4, 8 , 24
NOT SUFFICIENT
B) If n is a positive multiple of 6 it should be of the form 6*x where x is 1, 2, 3,4 etc therefore, n can be 6,12,18,24, etc
NOT SUFFICIENT
Both A&B ) n is multiple of both 4 and 6 i.e. it is of the form 4*6*x = 24*x
SUFFICIENT

Is the positive integer n a multiple of 24 ?
(1) n is a multiple of 4. (2) n is a multiple of 6.Sol: Is n= 24I where I is an Integer St 1: n=4a where "a" is an integer. Now If n=4 then no but n=48 then yes. A and D are ruled out St2: If n=6 then no if n=24 then yes. Combining we get n is muliple of 4 and 6 so n is a mulitple of 12 but need not be a multiple of 24...here's why If n=12,36,60 then not a mutiple of 24, but If n= 24,48 then Yes Ans is E

Difficulty level  500 Time Taken  00:17 Hi , Lets take a example of 12 or 36 ,both are divible by 4 as well as 6 but not by 24, so we cant conclude by both statements
