Folks,
Though intelligence is abundant to all cultures or geographies but in certain circles of society its nearly a practical consensus that Russians, CJK (coined from SW language patch for Chinese, Japanese & Korean), Indians have a way with numbers...! Here is the reason I say that…in my grad program.. at one of the “come clean my basement for free food and drinks” professor parties it became a very emotional subject… in order to win the battle …a lot of liquor was wasted on the so called intelligence… … and guessed rightly… intoxication was unmistaken winner not professor’s clutter…!
Had to make the background interesting so that you read further… But seriously lets see if we can use to it our advantage…
GMATClubbers are from every possible geography and culture (should start a Google map to indicate global demographical spread) and far more geniuses than just 3 in my tell tale above
I request to you all to provide your feedback to all Time saving Techniques\Short Cuts\Tips (beyond the formula cheat sheet) that you use or has aided your GMAT preparations… Here are some thoughts:
o Pythagorean Rules
o 30, 60, 90
o 45, 45, 90 (side ratio rules)
o Triplets (possibly the best example; does appear in GMAT fairly regularly in one way or another) … 27, 36, 45… (you know what I mean…)…
o 987 X 987 = (1000-13)^2 a neat application of (a-b)^2 …I bet someone must have also thought about (900+80+7)^2 if you knew (a+b+c) ^2
o Remembering a few fractional values (helps in approximation problems)
…imagine if you are lucky… and… any one can be used in real exam … you saved yourself ~2 mins…

DestinyChild,
Can you explain what types of problems use "Triplets" and how? Also, are you using the (a-b)^2 as a faster way to find the value of (987x987) or for some other purpose? Thanks.
