Is the question correct? 9/2 greater than or equal to 2?

Hi Bunuel bb gmatt1476

The question above needs to be modified. The inequality is 9/x ≥ 2.

Thanks!

The question asks for the least value that satisfies the inequality 9/x > 2

The quickest method is to test the answers

A. 9/0 = 0 but 0 is <2 not greater than 2...Incorrect
B. 9/1 = 9 9>2 this works.
C 9/4 =2.25 although 2.25 is greater than 2, 4 is not the least value for x that would make the inequality work

For this reason B is correct.

IMHO, regarding option A, we can just say that the denominator cannot be 0 at all! So there's actually no need to do any kind of calculation. Manager  S

option A :- 9 / 0 = undefined So option A is discarded.

Option B :- Put x = 1 and check .
9 / 1 >= 2 ...So option B satisfies the inequality.

Please give me KUDOs if you liked my explanation.

Guys is there a way to solve this using algebra and not by plugging in?

9/x >= 2, this inequality tells us that x can't be negative or 0, because in either case inequality is violated (Example : 9/(-ve number) is negative, 9/0 is undefined)
now solving the inequality gives us :
x<= 9/2
x<= 4.5
So the possible integer values are {1,2,3,4}, of which the minimum is 1 (answer)

Bunuel integer x is not specified to be either positive or negative.

Hence if x was negative the expression would become $$x>=9/2$$ --> least integer 4.

However, if we consider x being positive, the expression gives x=1 as least integer.

I think the question stem shoud specify that x is positive.

This is an official questions so it must and is correct.

If 9/x ≥ 2, then x cannot be negative, because if x is negative, then 9/x = 9/negative = negative and cannot be more than a positive number.

Hi All,

We're given the inequality 9/X ≥ 2. We're asked for the LEAST integer that satisfies the inequality. While this question is relatively straight-forward, it's written in such a way that you might lose track of what you're ultimately solving for. To reiterate, we want the SMALLEST INTEGER that "fits" the inequality.

We need 9/X to be greater than or equal to 2, so we need X to be POSITIVE. We are NOT asked to make 9/X as small as possible.

Thus, the smallest positive integer that 'fits' the inequality is 1.

PS41471.01

If 9/x is greater than 2, we know that x is POSITIVE

Since x is POSITIVE, we can eliminate answer choice A.
At this point, we can test values, starting with the smallest possible value.

B) 1
If x = 1, our inequality becomes 9/1 ≥ 2, which is TRUE
Done!

Cheers,
Brent

I'm curious to know why this question has been added to the GMAT Official Advanced Questions book! (Question No. 14) That book is meant to contain only hard questions lol. Or maybe according to the GMAT database a lot of people choose E?

We see that x can’t be 0 or negative (otherwise, 9/x will be undefined or negative, respectively). So x must be positive, and if x = 1, we have 9/x = 9/1 = 9 ≥ 2.

if the question asked for greatest integer then would 4 be the answer then ?

Hi mockingjay,

YES - if the question was changed and we were asked for the largest integer-value of X, then the answer would be 4.

Unbelievable, do you really think 9/0 undefined? It’s infinite and infinity is definitely greater than 2. If this is an official question, I question the test are we to understand that the test limits it’s understanding to algebra and so those of us who have a calculus background are at a disadvantage? Too bad. Bad question

in the case of calculus, x tends to 0, not actually 0. This is why infinity is considered. calculus doesn't really talk about absolute value in the cases. X is so small that it is nearest to 0 (we don't know what is nearest to any number), so in that case, dividing the above number from 0.0000000000000000000000000000000000000000000000......1 will give so big a value that it is considered infinite.
