There are many benefits to timing your practice, including:

The answer is C. Doesnt 3 and 4 both satisfy condition 1 and 2. So ideally we dont have any firm answer. 3! and 4! are not divisible by 5 and are divisible by 6

(1) x! is not divisible by 5 (2) |x|! is divisible by 6 The answer is C. Doesnt 3 and 4 both satisfy condition 1 and 2. So ideally we dont have any firm answer. 3! and 4! are not divisible by 5 and are divisible by 6

Please advice.

st 1) x can be 1,2,3,4. Not sufficient st 2) |x| > 2 . Not sufficient

I think it is A.because when x! isn't divisible by 5 so it must be 4! or 3! when it says that x is a prime number so it should be 3! so A is the answer. Am I wrong?

Is X a prime integer?

(1) x! is not divisible by 5 (2) |x|! is divisible by 6

Is factorial always an integer? can we have a non-integer factorial? Can factorial be negative? Someone please clarify.... if factorial is always an integer and positive, then 1. x=0,1,2,3,4 2. X=3,4,....

There is one piece that is missing from previous explanations:

Statement 2 suggests that X can be positive or negative because absolute value of |X|. Because X be either negative or positive (and we can't figure out which), that means that we cannot determine whether it is prime. For example, 3 is prime, -3 is not.
