(1) \(x = \sqrt{3}\)
(2) y is a prime number


1) X=\sqrt{3} Therefore X is aprox 1,73 Not sufficient considering that we do not know anything about y.

2) Y is a prime number, therefore y>=2 but X is unknown in this case so; Not sufficient.

Combined we got X= 1,73 ( APROX) , Y >= 2, So we got the answer; NO .
Is C for me.

Question : Is x greater than y?

Statement 1: \(x = \sqrt{3}\)
No information about y to compare with the value of x hence
NOT SUFFICIENT

Statement 2: y is a prime number
No information about x to compare with the value of y hence
NOT SUFFICIENT

Combining the two stataments
x=1.732 and Minimum value of y = 2 (Smallest prime number)
Hence, x < y
SUFFICIENT

Answer: Option C

(1) \(x = \sqrt{3}\) <----Not enough info alone
(2) y is a prime number
<---Not enough info alone


My logic

Prime = 2,3....so on lowest prime is 2
the square root of 3 is less that 2


with both together u can answer this

but alone NO
