#### OG 12 DS 112

###### Data Sufficiency

taking cue from Ian (who taught me so many things that if charged one dime per lesson it would buy him a 760Li by now :-) ), I am trying to enlist types of time-work problems that comes in Gmat. Please help me if I miss anything. 1. Comparison between independent efficiency like the problem above 2....

#### OG 12 DS 109

###### Data Sufficiency

Answer is A. it is tough to make you understand without a figure but think AC = 4 inches BC = 8 inches ax = 2 inches RC = . 5 inches SC = 2 inches. now as ABX and RSC are similar triangle AX^2/RC^2 = area of ABX/Area of RSC hence A wins. B can be any height if height on particular side was known, it...

#### Can You solve this "remainder" question?

###### Data Sufficiency

Basically,

the question is asking ...what is the unit digit of n

Using both statements independently,
each time unit digit is 5 (use VIC method)

hence D.

I have certain isuues with range for stmt 1. x^2> x implies x can be positive/negative integer also x CAN BE negative fraction so x can be 5, -5 or -1/5 stmt 2 says 1/x>0 now x can be +ve fraction or integer in both cases 1/x >0 therfore together, x can be only positive INteger hence the answer to i...

#### integer

###### Data Sufficiency

m&M ,

The problem is that

in b,

a^m < 1 hence m<0 as a is +ve int

k>m

so whaever the value of k (positive or negative) a^k is always > than a^m

hence choose D.

what is OA?

#### tricky odd/even integer question

###### Data Sufficiency

if this is of any help from stmt 1, xy +z +(x-1)z == even odd + (x-1)z == even hence (x-1)z is odd hence x-1 odd and z odd hence x even and z odd putting back in the original condition xy = even z =odd which satisfies the condition hence yes x is even, choose A/D for stmt 2, my reasoning is same as ...

#### Is it true that x>0?

###### Data Sufficiency

Hi Jose,

I can not get this stmt,

x can equal 0 or sqrt3 or -sqrt3
(0)^3=3(0)
(sqrt3)^3=(sqrt3)^3

stmt 2 says

x^3 = 3x

then why we are going for a avlue like 1.732 ? is not x an integer?

#### Std Deviation..

###### Data Sufficiency

whatever I have learnt from all the Ian Stuart's lessons,

SD is the spread from mean.
as long as you do not know the spread for both companies, no way you can answer which SD is greater hence E.
