6 Machines x 12 Days = 72 72/8 = 9 Machines 9-6 = 3 -->Additional Machines

2. 1x2x3x4x5x6x7x8x9x10x11 = 39,916,800 / 990 = 40,320 ----> INTEGER. 11 is the answer. 3. Women = 5! / 3! 2! = 10 Men = 7! / 1! 6! = 7 Total = 10x7 =70

Congratulations! And may I know of what reference did you use for Quants? Thanks.

IF IN HOURS Mine is 2x / 2y + 0.17 hrs. 10 minutes = 0.17 hrs. IF IN MINUTES Mine is 2x / 2y + 10 mins.

Exactly as what sushbis mentioned. Difference between 600 and 400 = 200 (200 represents 25%) 200 x 4 = 800 (100%)

You must have did something wrong because I also made a venn diagram and it is 17. 3,3,3 1,1,1 5 = 17

I don't get this. I just wish that people in here would show their solutions rather than giving only the answers. It's not helping anyone.

"Each Question is worth 2 marks each" Hilarious choice of words..............

I got it now.... Obviously nobody came to answer... Thanks anyway :)

I want a detailed explanation. Thanks! 1 . Is the triangle ABC an isosceles triangle? [ATTACH=CONFIG]5899[/ATTACH] (1) CD is perpendicular to AB . (2) ACB is bisected by CD . 2. What is the length of the hypotenuse of a 45°-45°-90° triangle ? (1) The area is 8 . (2) The perimeter equals 8 + 4 √ 2

I have the Official Guide 12th edition, Kaplan 800, Nova's GMAT Prep Course and some Manhattan books.

Do you think these questions are found on the GMAT? as I found these on an algebra book. (seems pretty hard though!)

Area of a Square s x s 6 x 6 = 36 Area of a Rectangle lw ?(2.5) =36 as it is equal to the area of a square 36/2.5 = 14.4 cm

thanks! Makes perfect sense.

I've answered about 40 problems and I'm stumped with this question, I know you guys can answer this in a snap the question is in here ( I would have typed it but it's better to see the actual diagram) IMG_0252.jpg picture by ultdm - Photobucket answer 1. (D) Using the coordinates of the points given, a right triangle may be constructed as shown. Notice that the horizontal length of the triangle is 6 ; its vertical leg is 8 . Therefore, it is a 3-4- 5 right triangle . Its hypotenuse (side AB) must be 10 . My question is that how did it come up with the horizontal length of 6 and a vertical leg of 8. A detailed explanation would be great! thanks!

1,002,001 / 13 = 77,077 b. 2

I think it's B. 7.20 As the problem states the lowest possible price of a toy costing $16 $16.00 x 40% - 16 = $9.60 $9.60 x 25% - 9.60 = $7.20 B.

I just used trial and error for this. I tried E. first, 360 x 6/10 = 216 480 x 4/10 = 192 total = 408 which is wrong I tried D, 360 x 6/10 = 216 460 x 4/10 = 184 total = 400 which is correct.

1st Journey Distance = rate X time = 40mph(2hrs) = 80 miles 2nd Journey Distance = rate X time = 80mph(3hrs) = 240 miles Sum it all up, 80+240 = 320 miles / 5 hours = 64 miles/hr

You're not making any sense. Tell us your score and its Q/V equivalents so as to determine your strengths/weaknesses... You might as well just quit if I were you or sign up at an expensive prep course, say Manhattan or Kaplan... See if that works out... Good luck!!!!!!! :D

Most prestigious US Colleges/Universities require a 3.3+ above GPA and note that this is just the MINIMUM, averaging of about 3.6-3.7. A 3.7 GPA? And a grammar like yours? Please go to a decent grammar school before posting anymore of your filth. How old are you? 12? I'm sorry but your grammar needs a lot of tweaking.
