Thread: Quantitative Comparison

Hi,

So I am given the following rules:

4<x<10
3<y<5

Quantity A
x+y

Quantity B
14

A) Quantity A is larger
B)Quantity B is larger
C) Both are equal
D) Not enough information to determine

Now, the answer is (D) - apparently. But I disagree.

The answer of x+y cannot under any circumstance be larger than 13, correct? The largest numbers X and Y can be are 9 and 4, respectively.

The solution in the book offers an explanation (which is basically adding those two rules above) of 7 <x+y < 15.

I don't see how this is possible....under the set of rules given, the largest number should be 13 (which would mean Quantity B is always greater)

This problem is found in Kaplan's GRE prep book.


****Nevermind figured it out -- was too focused on integers and discounted decimals ********

What if x = 9.75 (<10) and y = 4.75 (<5) ?

Thanks for reply...tried to delete this post because I figured it out soon after. I was entirely too focused on integers and didn't account for decimals. Brain fart
