Hi All,

PFA the document having all the six questions for DS. Please provide the answer for them so that i can understand the logic for calculation.

Thanks in Advance.

Hi my first post in the fforum...
let's go for question 2

if v and w are differents integers, does v=0?
1) vw=v²
2)w=2

E.

1) is insuf since we could have w=v=1, or v=0 and w = whatever.
2) is insuf. we know nothing about v

the two togheter are still insuf. w=2 ==> 2v=v² ==> v=0 or v=2

Hope i'm not wrong.

The answer to Question 1 is 'D'.

GCF of m & p is 2. m < p and m is not a factor of p. Tried with numbers I couldnt find a pair whose remiander is < 2
and also remainder when a number is divided by another is always the HCF of two numbers so 1 is SUFF

Second statement is SUFF which is = 1 in all possible cases, (unless i am missing any particular scenario)
LCM is 30 possible numbers are
(3,10) remainder 1
(5,6) remainder 1

***********************

The answer to Question 2 is 'C'

vw -v^2 = 0
v(w-v) = 0
v= 0 (or) w=v
donno for sure if v= 0 , NOT SUFF

w=2, NOT SUFF

put together , w=2 & w=v, hence v= 2. SUFF to tell that V <> 0

***********************************

The answer to Question 3 is 'C'

is x+ y < 1, both statements are clearly insuff, and then toghether we should be able to tell that the sum is always less than 1.

please confirm this!

*********************************

The answer to Question 4 is 'C'

A :NOT SUFF, Two of the interior anlges are right angles : that leaves us with sum of rest of angles is 180, clearly not enuf to say if one angle is 60 or not
B : Not SUFF, if one angle is x and the other angle is 2x, all i am able to deduce is 3x = 360 -(A+D)

from 1 & 2 clearly
3x = 360-(A+D)
3x= 180
x=60 SUFF

***********************************

The answers to Question 5,6 is 'E'. [will explain if some one raised it.]

*********************************

Good catch !



but given in the question that v & w are different integers which will rule out V=2

leaving us with v = 0. My answer is correct but not approach.

Thanks for correcting! The answer is still 'C'

Guys ... for the vq question .. answer is A ... I dont know how we can get to know by using the first statement if v can be zero or not.

Let me list down the answers for all questions here:

1. Question 1 : Answer is A
2. Question 2: Answer is A
3. Question 3 : Answer is E
4. Question 4: Answer is E.
5. Question 5: Answer is A
6. Question 6: Answer is B.

Please help me for all of them. Thanks in advance.

Oh skpMatcha, you're right for Q2, answer A is fine.....

for Q3

x+y<1?

1) x<8/9
2) y<1/8

the stmnts alone are not suff. we want to figure out what happens when put together.
8/9=0.88888888888.......
1/8=0.125

picking numbers:
x=0; y = 0 the answer to the question is YES
x=0.881 (<0.88888...) and y =0.121 x+y = 1.002 the answer to the question is NO

hence, the two are not SUFF.... answer E.

Are we allows to use decimals as I did?

Hello everyone. Nice to meet you all.

Yes you can use the decimals.
E is the correct ans

for Q5:

If you represent each area with digits,and make equations you will realise that A is sufficient to find the common area

pareekpuneet,

Thats not the way to post your questions/problems. If you post in such a way, you wont get the detail explanations and sufficient replies to your questions.

The best way is to post the question individually. If so, you will get many replies and detail disection of your question'.

Also it is not gmat club etiquette to post a buch of questions in a word file. If you are new to the forum, refer to the following link for how to post your questions and revele the OA/OE: etiquette-for-forum-participation-59508.html

Hope you understand my point.
