Thank you Anurag. The solution is awesome!
@Mitch: I kind of get excited when I see such challenging questions, and almost forget the plug-in concept! I should keep reminding myself about plug-in strategy when I get excited the next-time
Thank you.
Cheers,
Kunal

IMO the answer should be E New Hire = (University Grad) or (Son/Daughter of Employee) Fatima should fit into either of above options. If she were to be an University Grad, other option must be false. i.e; Her Father or Mother should not be working for Bennsoft. Since the passage mentions about her f...

The thing that worked for me, when I was in same situation as yours is: 1. Read each word carefully from the passage. 2. Focus on question. 3. If it asks strengthen, start thinking how it could be boosted. What point will actually make the answer seem more valid? (ofcourse, without looking at answer...

It just can't get better!
What a wonderful elucidation on the concept Ceilidh! I am now convinced these attributes are inversely proportional.

Thank you Brent. Appreciate your quick response.
Your answer reinforced my concept and now I know, I am thinking in right direction.
I will also check out your 'aside-notes' to make the concept crystal clear.

Combinatorics - Restaurant Menu!!
Hi, Most of us know how to solve the below problem: A restaurant menu features five appetizers, six entrees, and three desserts. If a dinner special consists of one appetizer, one entree, and one dessert, how many different dinner specials are possible? (5*6*3 = 90 different ways) I was curious to k...

You know GMATGuru, I plugged-in same values of 5,2 and 3. But, I was only stuck at a point where the functions are to be solved!
I realized, what a silly mistake I committed!
Thank you so much!

f(x+y) = f(x) + f(y)
For which of the following functions is
f(x+y) = f(x) + f(y)
for all positive numbers x and y?
f(a) = a^2
f(a) = a+1
f(a) = squareroot(a)
f(a) = 2/a
f(a) = -3a
can anyone please explain me the above problem?
Thanks in advance,

Smallest prime factor - tough one for me!
For every positive integer n, the function f(n) is defined as the product of all even integers from 2 to n, inclusive. If m is the smallest prime factor of f(100) + 1, then value of m is: between 2 and 10 between 10 and 20 between 20 and 30 between 30 and 40 greater than 40 Can someone please explai...
