Another day about to end....while all of us are working on a project.........A really discombobulated problem......after 3 hours of reading really do not know where to start........
Today let me talk about one of our Professor Saral Mukherjee......he is a great teacher knows how to drive the concepts home......in a very lucid way........
At IIM he says that students get to see the early morning sun.......Not because they have woken up early but because the poor souls have not got a chance to sleep........:) we are experiencing it...........
BTW I was talking about organizations being elephants and organizations being active like cheetah's......Our class is awesome and innovative..........A student brought across a point of Lazy Cheetah.....wow the professor was also astounded...........really imaginative class............
Just came to know one of our Professors teaching us is the official negotiator at WTO for India..........wow he teaches me economics......
From the groups experience I would say that though the going is tough but slowly slowly the tough gets going........
Now lets come to todays GMAT Problem highlight below for the OA.
If y is an integer, is y^3 divisible by 9?
(1) y is divisible by 4
(2) y is divisible by 6
OA is B

(2) y is divisible by 6
OA is B
Solution :
ReplyDeleteSimple approach : Pick numbers.
1) y is divisible by 4 ► y can be 4 , 8 , 12 etc.
Negative o/p : Check for 4 : 4^3 not divisible by 9
Positive o/p : Check for 12 : 12^3 divisible by 9
Result : Cannot determine.
(A,C,D Ruled out)
2) y is divisible by 6 ► y can be 6 , 12 , 18 etc.(hmmm i see that prime factor of 6 , 12 and 18 always has 3 and hence 3^3 will always be divisible by 9)
Positive o/p : Check for 6: 6^3 divisible by 9
Positive o/p : Check for 12: 12^3 divisible by 9
(E Ruled out)
Hence correct answer : B
