1) x is a prime number.
X can only take the value of 31. Now Y can be either 31 or 32, 33, 34 , 35. Now since whatever be the value of Y, value of X will always be less than or equal to that of Y. Hence Statement 1 is sufficient.
2) sum of digits of y is 8.
Y can only take the value of 35. Now X can either be 35 or less than 35. But X cannot be more than 35.
Hence the answer to x>y is No. Statement 2 is sufficient.
Answer is D

1) x is a prime number.
X can only take the value of 31. Now Y can be either 31 or 32, 33, 34 , 35. Now since we don't know the value of Y, this statement is not sufficient.
2) sum of digits of y is 8.
Y can only take the value of 35. Now X can either be 35 or less than 35. But X cannot be more than 35.
Hence the answer to x>y is No. Statement 2 is sufficient.
Answer is B
What if X=Y then as per option B x<=y which is same as option A. Both statement is sufficient to answer whether x>y or not. X can only take the value of 31. Now Y can be either 31 or 32, 33, 34 , 35. Now since we don't know the value of Y, this statement is not sufficient.
2) sum of digits of y is 8.
Y can only take the value of 35. Now X can either be 35 or less than 35. But X cannot be more than 35.
Hence the answer to x>y is No. Statement 2 is sufficient.
Answer is B
So ans is D.
Please correct me if I am wrong.
