Hi Dave, thanks for the detailed solution. I too have seen problems like this where approximation normally works great. But, when I approximated here: sqrt(23)=4.8, which is very close, I found 5*sqrt(23)=24, which makes the 2nd expression ZERO and X<7. Do u think its a good idea to do all those ste...

Thank you so much, Mitch. Now it is crystal clear.
I was overthinking, I guess.

Thanks Mitch and Brent, I think I couldn't make myself clearer in the earlier post. I was basically solving it in Brent's method and the doubt I felt is: total # of possible outcomes Select 3 jars from all 9 jars Since order does not matter, we can use combinations.

SHE vs HER : the relative pronoun WHOM (who, whom, which, that, whoever, whichever etc. are called relative pronouns ) replaces she/her, so to check which one is correct replace WHOM with...

Thanks for clear explanation, Mitch.
I got this prob correct but there was a gap in understanding.
Do you find this Question GMAT-like? If yes, which category should it lie? Strengthen?

CR 300: Yeasts capable of leavening

Q. Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally. The Egyptians, however, did not discover leavened bread until about 3000 B.C. That...
