If x and z are positive integers and xz = 24 what is the ratio of x to z?

(1) x/6 is an integer.

(2) z/2 is an integer

Given = x*z = 24

Question = x/z

We can do it by factorizing 24,

24 * 1

12 * 2

8 * 3

6 * 4

Statement 1: For x/6 = integer , then x can take three values 24, 12, 6. No info about z = Insufficient

Statement 2: For z/2 = integer, then z can take six values 24, 12, 8, 6, 4, 2. No info about x = Insufficient

Combining 1 & 2 will give us various values of x and z, and different x/z ratios. So combining also Insufficient

(E)
