Question:

If 2x = 4y = 8z and xyz = 288, then find the value of x.

Options:

4

6

8

12

Correct Answer:

12

Explanation:

(2)x = ((2)2)y = ((2)3)z

2x = 22y = 23z

So, in this condition, if base is same, then power will be equal

x = 2y = 3z

x = 6R

y = 3R

z = 2R

Now, xyz = 288

6R×3R×2R = 288

36R3 = 288

R3 = 8

R = 2

x =6×2 = 12
