Gprabhumir SHRAVYA007 That’s not right. Mathematically, \(\sqrt{...}\) is the square root sign, a function (called the principal square root function), which cannot give negative result. So, this sign (\(\sqrt{...}\)) always means non-negative square root. The graph of the function f(x) = √x Notice that it’s defined for non-negative numbers and is producing non-negative results. TO SUMMARIZE: When the GMAT (and generally in math) provides the square root sign for an even root, such as a square root, fourth root, etc. then the only accepted answer is the non-negative root. That is: \(\sqrt{9} = 3\), NOT +3 or -3; \(\sqrt[4]{16} = 2\), NOT +2 or -2; Notice that in contrast, the equation \(x^2 = 9\) has TWO solutions, +3 and -3. Because \(x^2 = 9\) means that \(x =-\sqrt{9}=-3\) or \(x=\sqrt{9}=3\). Hope it helps.
Thank you very much @Bunuel!

If I my logic is right. I am not gonna give you a direct answer but rather in order to get you to frame your mind. I am gonna ask you.
How do you know if p>q? How do you get the value of both p & q?

I am myself struggling with the logic of DS at times so hoping others would correct me if I am giving the wrong input

Please solve this question.Someone posted it in a gmat related group.

In a multiple choice question containing 10 options, students are informed that t of the options are correct. Student must select all correct options in order to receive credit. For what value of t would the student be least likely to receive credit on the question, assuming the student guessed randomly?

A number when divided by a divisor leaves a remainder of 24. When twice the original number is divided by the same divisor the remainder is 11. What is the value of the divisor?

Can anyone help with this question?

Assume that the dividend is x, and the divisor is y

Rem(x/y) = 24; Inference ⇒ y > 24

Rem(2x/y) = Rem(x/y) + Rem(x/y) ⇒ Expected Remainder = 24 + 24 = 48

However, we see that the remainder is 11. Which means that the remaining value must have been the product of a quotient * divisor.

Remaining value = 48 - 11 = 37. As 37 is a prime number, the possible way to arrive at 37 is 37 * 1. So the divisor is either 1 or 37. We know that the divisor is greater than 24, hence 37 (also if the divisor were 1, the remainder will always be 0)
