Back to paper

x, y and z all are positive number. If 3x > 9y and 2y > 4z, then which of the following is TRUE?

Show answer & explanation

Correct answer: A

Explanation

The correct option is 1.

if we consider : 3x > 9y , then x must greater than y and x must greater than 2.

Let say, x = 7 and y = 3 , it implies that 35 = 243 > 92 = 81.

again, if we consider : 2y > 4z then y must greater than z and y must greater than 2.

Let say, z=1, So, y=3 is greater than z.

So, it must be : x > y > z.

A is correct choice.
