GMAT: Data Sufficiency 1

In problem #5 at 10:19... n could have equaled 8 or negative 8... not that it matters.

if i got same answers from the two given statement , I PICK each statment alone is sufficent ?

and if i got different answers also i said
statment alone is sufficent ?


HOW COME ?

God bless you for doing this series. You deserve a medal.

is this from the 10th or 11th edition?

11th

DATA SUFFIEICEY IS ALWAYS A PIECE OF CAKE FOR ME..

ALL THAT MATTERS TO ME IS SENTENCE CORRECTION !!
i solved the above just in my min in only 1 sec :D :P !

"InteRgers" (9:25)... unless you're a New Yorker.

data sufficiency is not on the SAT. it is where they give you an equation and two statements and you have to decide if you can answer the question based on one or both of those two statements. you arent necessarily answering the problem just deciding if its possible to answer it.

Not sure what exactly data sufficiency is,
but if it deals with partial percentages/angles and solving for the other half, it is on the sat.

But yeah, since its the GMAT i know its harder than the SAT...but this seems so easy...
then again the sat seems easy to, its only the timing that makes it so hard
