right said 800Bob[clap]

Good catch 800Bob. I think I gotta be careful in evaluating this kinda tricky Qs. However careful as I may- I'm sure I'm gonna slip out one or two- I vaguely recall seeing a similar Q in OG where the answer was based on what Karmaholic had explained. ------------------ Oh... I just found that in OG Q, it is clearly mentioned that n is an integer where as in this Q it is not. So 800Bob's explanation stands valid.

agree with karmaholic.

something wrong in the Q stem. so don't look at the figures that I hv put below. I put the figures generally to reach at the answer as 60. in general, the way to solve this kinda Q is: given E/N=20/11 => E = 20k, N = 11k (k is any constant) If 7 more non-employees join then the ratio becomes 3/2 => E/(N+7) = 3/2 => 20k/(11k+7) = 3/2 => 40k = 33k + 21 => 7k = 21 => k = 3. so total number of Es = 20k = 20*3 = 60

though the avg GMAT score for ISB is 690, only 40~50% of applicants generally have GMAT score 700+. So I would say 680 is a very competitive score. you may want to join the yahoo group(isb-pgp@yahoogroups.com) for discussions on topics related to ISB. good luck for ur apps.

I came up with the equation as y-2 thanx 800Bob for ur response.

pricha, if u look at the Q stem you wud know that n=p/q from stmt1=> n^2 is an integer means p^2/q^2 is an integer where p,q both are positive integers. that means n^2 can't be 2/3/5.... it'll always be a perfect square

OA as I vaguely remember was C.

D. stmt1=> if n^2 is an integer then n has to be an integer. sufficient stmt2=> (2n+4)/2 is an integer => n+2 is an integer => n is an integer

great approach. actually i was looking to see if it can be solved in a much better way. thnx for the same.

is xy>0? 1) x-y>-2 2) x-2y

when positive integer n is divided by 3 the reminder is 2; and when positive integer t is divided by 5 the reminder is 3. What is the reminder when the product nt divided by 15? a) n-2 is divisible by 5 b) t is divisible by 3 can someone explain the shortest method to get the answer??? i tried substituting values for n & t stmt1 : n=> 17, 32, 47... and t=> 8, 13, 18.... stmt2 : t=> 18, 33, 48... and n=>5, 8, 11..... and finally from both the stmts I got the values for n=>17, 32, 47..... and t=>18, 33, 48.... .... .... from the above 2 list, can we find out the reminder when the product nt divided by 15?? the answer is given as C

I think A is the right answer. Correct usage of Forbid is Forbid to and not Forbid from

Hi Score800, given that the median is 130,000. It not necessarily means that at least one of the values will be less than this. It can be so that all the first 8 values be 130,000 each and still have the average as 150,000 and median as 130,000. Hope that helps....
