We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:

(1) \(x<\frac{8}{9}=\frac{64}{72}\). Not sufficient by itself.

(2) \(y<\frac{1}{8}=\frac{9}{72}\). Not sufficient by itself.

(1)+(2) \(x+y<\frac{64}{72}+\frac{9}{72}=\frac{73}{72}\) --> \(x+y<\frac{73}{72}>1\). So \(x+y\) may or may not be less than 1: \(x+y\) could be less than 1 as well as more than 1, in the range \((1,\frac{73}{72})\) or even equal to 1. Not sufficient.

(1) \(x<\frac{8}{9}=\frac{64}{72}\). Not sufficient by itself.

(2) \(y<\frac{1}{8}=\frac{9}{72}\). Not sufficient by itself.

(1)+(2) \(x+y<\frac{64}{72}+\frac{9}{72}=\frac{73}{72}\) --> \(x+y<\frac{73}{72}>1\). So \(x+y\) may or may not be less than 1. Not sufficient.

Answer: E.

Thank you Bunnel...I made a silly mistake by taking x and y eqaul to the values given in the problem...I need to read the problem carefully...Thank you again

I'd rather not see GMAT Prep questions on the forum though. Like others in verbal forum say, it might skew our score in doing the prep ourselves..

I like them in the forum, because there is no explanations given in GMAT Prep. As long as the post is tagged, you should be able to avoid clicking and seeing GMAT Prep questions.

Dude don't post the answer above the question in your post. Posting the answer farther down allows others to attempt to solve the question without knowing the answer beforehand.

It helps not to look down or scroll down while you are attempting to solve the question.
