A. 2 B. 3 C. 4 D. 5 E. 6
M1001 \(x3.5 \lt 2\) means that \(2 \lt x3.5 \lt 2\). Now, add 3.5 to all three parts: \(1.5 \lt x \lt 5.5\). Since given that \(x\) is an integer, then it can take the following four values: 2, 3, 4, and 5. Answer: C

Thanks Bunuel, But I did not understand this part x3.5 < 2 means that 2 < x3.5 < 2Bunuel wrote: sunita123 wrote: How many integers \(x\) are there so that \(x  3.5 \lt 2\)?

I guess this is the same as doing this?
x3.5<2 x3.5<2 x<5.5 and,
x+3.5<2 x<23.5 x<1.5 x>1.5
Both together: 1.5<x<5.5
So, x can be 1.5, 2.5, 3.5 or 4.5 (0r in fact 2,3,4,5 since it is an integer). Is this the solution?

Hi All, Sometimes the easiest/fastest way to get to the correct answer is to use "brute force"  you can literally just jam numbers into this question until you physically find all of the answers. Children can do it, so you can do it. The prompt asks for all of the INTEGER values of X that fit X  3.5 < 2. From the answer choices, we know that there are at least 2, but no more than 6, possibilities. The first answer you will find is probably the easiest: X = 4 4  3.5 = .5 which IS < 2 Now, let's go "bigger" X = 5 5  3.5 = 1.5 which IS < 2 X = 6 gives us... 6  3.5 = 2.5 which is TOO BIG. So X CANNOT be 6 and it CANNOT be > 6 Let's go "smaller" (from X = 4) X = 3 3  3.5 = .5 = .5 which IS < 2 X = 2 2  3.5 = 1.5 = 1.5 which IS < 2 X = 1 1  3.5 = 2.5 = 2.5 which is TOO BIG. So X CANNOT be 1 and it CANNOT be < 1. The values of X that "fit" are 2, 3, 4, and 5 > 4 integers. Final Answer: GMAT assassins aren't born, they're made, Rich

M1001 \(x3.5 \lt 2\) means that \(2 \lt x3.5 \lt 2\). Now, add 3.5 to all three parts: \(1.5 \lt x \lt 5.5\). Since given that \(x\) is an integer, then it can take the following four values: 2, 3, 4, and 5. Answer: C The rule is : lxl<a =>, a<x<a Here, x=x  3.5 and a=2

x3.5  < 2 2 < x  3.5 < 2 1.5 < x < 5.5As per above statement, and as x is an integer. x can take values of 2,3,4 & 5 Hence, Answer is C
