Was it you who said: 2) How many integers n are there such that 1 <5n + 5 < 25? Satisfy the equality, so that multiplying 5 times the integers you can multiply times 5, plus 5, are not less than one, but less than 25. For example, -2 times five is -10, plus five is -5, and that wouldn't satisfy the equality. -1 does. The integers are -1,0,1,2,3. The number 4 wouldn't fit, if you try it. A) Five I don't think -1 would work either. I myself missed zero, but -1 would not satisfy the parameters. 1 Must be less than (5n + 5) and if n = -1, then that becomes (-5 + 5) which becomes zero, which is not greater than 1. Unless I am missing something here... I didn't count zero in mine, so I chose 3, but if zero is included, then the answer should be 4. I think.
ok here are my answers. I dont know if you've posted the right answers yet, since I havent read the entire thread. 1. E 2. B (if those signs are less than and equal to), C (otherwise) 3. D (I didn't use a calculator, just an approximation) 4. D 5. A (complete guess, I had no clue) 1. A 2. A 3. C 4. D 5. A ok, now I'm gonna go see if you posted the right answers...
I forgot my GMAT book at home. I will post them later. This is a chance for you guys to use your brain today! :-D My thoughts, exactly
Bump. Lady_Di, where's the answers? I want to know exactly how much my brain has deteriorated since graduating. Your quiz is the only way I'll ever know!
hmm, you said you agreed with me except 1/2 on the sentences, but then edited 2 & 3 on the math? Read some thread explanations in the middle there?
I'm not pulling a Almu on this... I don't have my book with me today. I will try to post tonight or take the book tomorrow to work. I think most of you guys got them right.
I sent these questions out to my coworkers earlier... They already dislike you without even knowing you. (Or me, since I didnt say where the questions came from)
Okay here are the answers... You're either smart or dumb! Math section 1) E 216/9 = 24 2) B 1 <5n + 5 < 25 -4 <5n < 20 -4/5 <n<4 There are four integers between -4/5 and 4, namely 0, 1, 2, 3 3) D 16/ 2 + 16 16/ 2 +6 = x/144 16/18 = x/14 8/9 = x/144 9x = 1,152 x = 128 4) C Let M be Mary's income, T be Tim's income, and J be Juan's income. Mary's income is 60 percent more than Tim's so M = T + 0.60T = 1.60T SInce Tim's income is 40 percent less than Juan's income, Tim's income equals 100-40= 60 percent of Juan's income, or T = 0.60J. Substiuting 0.6J for T in the first equation gives M = 1.60(0.6J) or M = 0.96J. Thus Mary's income is 96% of Juan's income. 5) E Let w be the amount of Mary and John's same hourly wage. To set their hourly pay equal, John who worked 10 hours, needs to be paid 10w, and Mary, who worked 8 hours, needs to be paid 8w. Since Mary gave John y dollars, Mary now has x - y dollars and John now has x + y dollars. THeir pay can thus be expressed as follows: x - y = 8w Mary's pay x + y = 10w John's pay Subtract the first equation from the second and solve for w. 2y = 2w y = w substitue y for w in the second equation, and solve for x, the amount each was paid in advance x + y = 10y x = 9y English section 1) A 2) A 3) C 4) D 5) E
hmm... I got three of them wrong: Math #2) crap! I forgot that zero is an integer Math #5) I actually meant to type D. That sounds lame, but it's true. English #3) yup. Got that one wrong.
Missed 2.. both on Math for someone that did "really well" on the Math section of the SAT and the GRE.. #2) paid the price for trying to do it in my head...I forgot that I was dividing 20 by 5 and divided it by 4 instead...hence had 0 1 2 3 and 4 as my answer. (< 5) #3) never really got it. Still don't, in fact, but I think there are some numbers missing in your answer.. Got all the grammar questions..
1 wrong in math, 2 wrong in grammar. twice as bad in grammar just like high school, some things never change. got math #5 wrong. would have eventually figured it out but it was taking up too much time doing it. When I think of or say the word "seen" its always like "HAS seen", so maybe that word isnt always necessary...or necessary always, or whatever...
