Is x>2? St 1: x^2 > 4 => x can lie in two regions. x < -2 and x > 2. Hence not sufficient. St 2: -1 x can be greater than 2 and also less than 2 in this region. Hence Not sufficient. Combining two Statements, x lies in 2

KS15 · Answer

Statement 1: x^2 is greater than 4. If x^2 is 9, x can be 3 or -3. Insufficient
Statement 2: x is between -1 and 3. Insufficient
Using both statements, for if x^2 is greater than 4 and x lies between -1 and 3, then x has to be greater than 2
Answer C

Bunuel · Answer

800score Official Solution: The statement (1) tells us that x² > 4. That means that x < -2 or x > 2. Therefore the statement (1) is not sufficient to answer the question. The statement (2) tells us that -1 < x < 3. It is not sufficient to answer the question, because x can be 0, which is not greater than 2, or it can be 2.5, which is. The both statements combined give the following system of the inequalities: -1 < x < 3 x < -2 or x > 2 The solution to the system is: 2 < x < 3 Therefore x is definitely greater than 2. The correct answer is C.

AbdurRakib · Answer

Question is x>2?

Statement 1 : value of x could be positive and negative to be x^2>4, Insufficient .So I need to know more information
 Statement 2 : between -1 and 3 ,only x>2 values within this range valid to be >4(example: 3^2>4)  Insufficient  too obviously.

So,Statement 1 and 2 together makes the  Correct Answer C  for me
