Yes it's D The equation for a line y=mx+b, but I have difficulty using it Does x=0 mean that a line doesn't intersect the y-axis and y=0 doesn't intersect with x-axis??? Where can I get some information and examples????

Can anyone help me with using the line equations???? The example from OG: In the rectangular coordinate system (see attachment), the shaded region is bounded by straight lines. Which of the following is NOT an equation of one of the boundary lines? (A) x=0 (B) y=0 © x=1 (D) x-y=0 (E) x+2y=2

IMO C! What's the OA?

Imo D! (assuming that the picture is drown to scale)

Oops I skimmed the question and got the wrong answer! V_GMAT is right!!!!! Same approach!

Imo B

Agree with OA 1st statement consuders ABSOLUTE values of y and z, therefore if we take the real values y can be less then z - INSUFFICIENT 2nd statement points out that x is less than 0, but doesn't mention the values of y and z - INSUFFICIENT Both statements are also insufficient because we stil don't know whether y and z are positive or negative

Oops! Just in case this link won't work: CAT 2008, CAT 2009, MBA 2008, GMAT 2008, MBA preparation, CAT Training, CAT paper, CAT Results, IIM, XAT, problems, math, quant, verbal, data interpretation, reading comprehension, sentence correction,critical reasoning, number system, geometry,

Sure!CAT 2008, CAT 2009, MBA 2008, GMAT 2008, MBA preparation, CAT Training, CAT paper, CAT Results, IIM, XAT, problems, math, quant, verbal, data interpretation, reading comprehension, sentence correction,critical reasoning, number system, geometry, you'll find 1000's PS, DS, but don't waste your time trying to download CR,SC and RC - those archives are empty or broken! Have fun!:)

I also came up with E, but the OA is D.....

If n and p are different positive prime numbers, which of the integers n^4, p^3, and np has (have) exactly 4 positive divisors? (A) n^4 only (B) p^3 only © np only (D) n^4 and np (E) p^3 and np

A certain theater has 100 balcony seats. For every $2 increase in the price of a balcony seat above $10, 5 fewer seats will be sold. If all the balcony seats are sold when the price of each seat is $10, which of the following could be the price of a balcony seat if the revenue from the sale of balcony seats is $1,360 ? (A) $12 (B) $14 © $16 (D) $17 (E) $18

E for sure! V_GMAT, in the sake of the GMAT we always consider 0 to be even number!

IMO A We have 5 teams, which play with each other exactly once 7 of the games were already played 2 out of 7 games ended in a tie we have 3 games left: BD, BE, CE If none of these 3 games ends in a tie: 2 out of 10 is 20%, therefore 10% cannot be the percent of games played that ended in a tie. We can also check the other variants: If 1 of 3 games left ends in a tie - 30% If two - 40% If three - 50%

what is this set about ? It's the 1000 PS questions 42 sections 20 or 16 questions each u can download them for free ( but I couldn't find sections 9 to 20) is there a similar one for DS ? yep! and for SC, CR and RC too!

Does anyone know where it is possible to download the full set of PS 1000 ? The one I have lacks sections 9 to 20. Thanks in advance.

Thanks Praso!

Q1 IMO-20, since you have n= 1*2*3*4....*19*20, 2 and 20 are included, thus being factors of n Q2 It's D! t= -1, therefore -1+2=1 is in the set; 1+2= 3 (not minus 3) is in the set and 3+2=5 is also in the set. Q3 IMO-6 Solved by picking numbers: 1/6+1/4=5/12 (in 1 day, working together) 5/12*3=5/4 in 3 days, together I used this approach because the numbers were easy, any suggestions on how to solve it faster will be highly appreciated!

IMO B P1 - employee with salary grade 1 P2 - employee with salary grade 1 P1= 9,5+0,25(1-1) = 9,5 P2= 9,5+0,25(5-1) = 10,5 Difference=1

IMO B 1 - 145 is divisible by 36, as well as 181 - insufficient 2 - 180 is the only even integer divisible by 45 - sufficient

!!!!! correct !!!!!! [clap]

Right! We have to find PR !

3 for sure! the same approach

Sorry for links! I'd better start a new thread with properly attached images.

Ok! Thanks! I guess there is no way to escape that diagram.....
