I blew this one.

If three-quarters of the seniors major in one of four subjects => 300 guys majored in one subject. Didn't quite understand that it's 300 distributed over 4 subjects.

E is the correct answer, but i thought it should be C. from statement 2, (m+v)^2 = 25. so, (m+v) = + or -5. from statement 1, mv=6. Since m and v are integers, they can be, 2 and 3 or 6 and 1, but only the values 2 and 3 satisfy the first statement. So, m+v = 5. So, both statements together are suf...

x/y < 2 From stem 1 x- y < 2 For this to be true both x and y have to be negative . If that's the case then 3x+2y is always < 17 - Sufficient. 2. y-x < 2 ; x<2y : For this to be true x is +ve and y is -ve always .. hence insufficient. Choose A. I doubt this is correct - but gave it a shot. - pradee...

A simple one - but I got screwed never the less .. the modulus got me. I was like x > y when y > 0 and x > -(-y) when y < 0 .. so .. lesson learned :)

I took a different approach of picking numbers : Viz even and odd >6 as any number > 6 should be either odd or even.

Try with 7 - Eq 1 holds good.
Try with 8 - Still holds good.

Stop here. I'm not sure if this is the right way of doing this. DanaJ's approach is definitely better

Now that I think about it, I guess you are right. The only shortcut techniques I know of are backsolving and picking numbers. However, by default I use the traditional technique, will not be able to solve the problem, lose time, get demoralized and completely forget to use any other short cut techni...

Quant Strategy

Having an engineering background, I hate to say that I score better in verbal than in Quant. Just took the MGMAT CAT 3 and got a 70th percentile in Quant and 77th percentile in Verbal. Not to mention, I've exhausted all Quant resources I have. I haven't tried the purple OG yet. Though there has been...

Wanna be Entrepreneurs

Have a look at this 2004 video of William Sahlman with Charlie Rose. It's awesome. Sahlman is of course world renowned for his Entrepreneurship lectures at HBS. The story of battery operated toothbrushes is particularly interesting.
