it's difficult to tell which problem someone's talking about when a new post comes in. it'd be much better to have a separate thread for each question...

it may be a sad fact that that's solely why many people want to be traders, but still the truth is traders do party. I've experienced it first-hand on many a trip to Chicago ;)

he must have done something more than just make a video to get fired. when you're in finance, bottle service comes with the territory.

from the given info you know "other stuff" is 1%, i.e. 1 pound. that 1 pound of other stuff stays 1 pound of other stuff because only water evaporates. it becomes 2% of the total, so 98% (=49*2%) is then 49*1=49 pounds, so the total is 1+49=50 pounds.

what a kill-joy

ohh, hilarious!

you're right, the upper limit should be 9; I've changed it and now it's entirely correct. I don't see how my formula is not simple though. in fact, it's simpler than the initial description because all you do is plug in values for x and y and get a number as a result. remember, a formula should...

i didn't actually see it. but now that i looked, your solution does use the same approach (and it's really the *only* approach to get a formula...) but doesn't completely describe how to get all solutions... if you want a formula (and this can be easily deduced from my last post), it would be...

the question i'm assuming is asking for 4 digit numbers satisfying this property? the statements "first two sets of numbers" and "middle two sets of numbers" aren't precise otherwise. so you're looking for numbers abcd. 10a+b+10c+d=10b+c, which can be rewritten 10a+d=9(b-c). Note that the...

Yeah. Apparently he doesn't care for material possessions and leads a really modest existence. When he discovered the proof, he just posted it on the Internet for all to see.

This is pretty old news ...

Statistics, Probability and Combinatorics are very good subjects to show strength in (and usually necessary). Also pick up a book on brain teasers and/or Olympiad-type mathematics to improve your problem-solving abilities; this sort of thing is ubiquitous in quant interviews.

if it's gonna be food, it should be sushi :)

Instead of being an adjunct (or in addition to it), you may as well acquire your own private tutoring gigs and charge 80/hour or more.

MetroPCS advertises $40 unlimited call, text, and web, but i have no idea how reliable their service is. I personally use ATT, which has great coverage.

The problem doesn't require any sophisticated mathematics. The first statement merely implies that xy has at least 6 factors (since it can be factored in at least two ways as a product of distinct numbers greater than 1), while the second statement implies that for any pair (a, b) of numbers...

hi guys. count me in too.

the most important thing is to be sincerely passionate and persistent. the top programs are interested in people who demonstrate these qualities. your GPA alone or your GRE alone won't guarantee either a positive or negative response -- it's the over-all picture you present. show a commitment to...
