Is x a positive number?
Source: Beat The GMAT — Data Sufficiency |
Statement 1 says x+6>2, thus x>-4, not sufficient
Statement 2 says -5>x>5
Combining them does nothing.
Choose E.
Statement 2 says -5>x>5
Combining them does nothing.
Choose E.
1. x > -4
2. x^2 > 25
(+ or - ) x > 5
-x > 5 or x > 5
x < -5 or x > 5
1. Not sufficient
2. Not sufficient
1 & 2
x > -4 and (x<-5) => not possible
x > 4 and x > 5 => x>5
That is, x = +ve
IMO C.
2. x^2 > 25
(+ or - ) x > 5
-x > 5 or x > 5
x < -5 or x > 5
1. Not sufficient
2. Not sufficient

First of all, Karmayogi analyzed the Statement 2 correctlymals24 wrote:E for me as well
St 1: x>-4..insuff
St2: -5<x<5..insuff
Combining we get: -4<x<5..insuff
So E.
2. x^2 > 25
(+ or - ) x > 5
-x > 5 or x > 5
x < -5 or x > 5
Now lets combine these two lines
..........-4.........0.................................
.....-5...............0....................5............
X>5
I would say C

Stmt I
x > -4
could be positive or negative
INSUFF
Stmt II
x^2 > 25
|x| > 5
could be positive or negative
INSUFF
Together:
x > - 4
|x| > 5
x has to be greater than +5
I would go with C too.

x > -4

x^2 > 25too selected C as my answer, but the OA is given as E.
if x^2 > 25
then x> +5 or -5 i.e. x>-5 or x>5. Is this not correct? How is it that combining both the statements is not sufficient to answer the question?
|x| > 5
x>5 or x<-5
Since x>-4 is given x>5
The 2 statements will never contracdict each other i.e they will have something in common
x>-4 and x>5 is the common thing between stmt I and II and they dont contardict i.e something can be greater than -4 and 5 at the same time.
Probably we can request Ian/Stuart to clarify the C or E part for us.
Regards,
Cramya
Can u double check the question?
If stmt II was x^2<25
|x| < 5
x<5 x>-5
-5<x<5 would hold along with x>-4 which will make it insufficient leading to E.
If stmt II was x^2<25
|x| < 5
x<5 x>-5
-5<x<5 would hold along with x>-4 which will make it insufficient leading to E.

Unfortunately, I did not make any mistake in posting the question as is. The source is princeton guide. Its an exercise question with no explanation to the answers. If there are no answers that support E, I will assume that it was a mistake in the book.If the answer is E, the book has a typo as described by Cramya.cramya wrote:Can u double check the question?
