Analytical Reasoning

There are 5 houses in 5 different colors in a row. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage. Other facts
:1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the immediate left of the white house.
5. The green house's owner drinks coffee.
6. The owner who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
8. The owner living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The owner who smokes Blends lives next to the one who keeps cats.
11. The owner who keeps the horse lives next to the one who smokes Dunhill.
12. The owner who smokes Blue masters drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The owner who smokes Blends lives next to the one who drinks water.
The question is: WHO OWNS THE FISH?

I think many of us are aware of divisibility rules but the question is..." why this method?".So let us find out the answer.
1) let's take a three digit no.(rule for 3)
abc=100a+10b+c
= 99a+a+9b+b+c
=(99a+9b)+(a+b+c)
=9(11a+b)+(a+b+c)

now can we say that one part of number is a multiple of 9 and if it is then, number will also be divisible by 3,so we are checking the sum of the digits, which if becomes a multiple of 3 then the complete number also becomes a multiple of 3.


2)lets take a four digit no.(rule for 11)
abcd=1000a+100b+10c+d
=1001a-a+99b+b+11c-c+d
=(1001a+99b+11c)+(b+d)-(a+c)
=11(91a+9b+c)+(b+d)-(a+c)

now can we say that one part of a number is a multiple of 11,so we are checking the difference between the sum of the even and odd places ,if difference comes out to be the multiple of 11 then the entire number is divisible by 11.

3)let us check the divisibility of 7 and 13.(method is same for both 7 and 13).
Take an eight digit number as abcdefgh,now make the sets of three from right to left and then take the difference between the sum of the alternate sets,if the set is not complete put zero before the number.If difference is zero or multiple of 7 or 13 then the number is divisible by 7/13
(fgh+0ab)-(cde)=0 or multiple of 7 or of 13.

CONCLUSION:Any six digit no like(111111,222222,333333........)is always divisible by
7/11/13.For 11 also you can use the same method.


Now the question for you that why we make the sets of three in case of 7/11/13.
post your answers and have a coffee with me.

Para Completion Deciphered

Well I am back after a considerably long hiatus.This time I am going to give you all some dope on the Verbal Logic section.This is for all the CAT-08 aspirants who have been burning themselves out on questions from Para completion.This section has been quite ubiquitous in CAT for the past two years and is very probable in 2008 as well.The biggest challenge,that the takers face here is the ambiguity of the options.The point to be kept under consideration is that,the question will generally require you to "Choose the best possible answer" which insinuates that there exists a possibility of more than one correct answer.Now what to do?Again in a conundrum!There is no need to fret!Remember there are certain yardsticks that one can use as a checklist to strike-off the options that do not seem to fit in perfectly.For example,one or two options can be clearly negated on account of being"Out of Scope",i.e. not being in direct relation to the context.Same rule applies to an option that seems to regurgitate the same idea mentioned in the passage(That would rather qualify as the summary).Remember your correct option will NEVER be a restatement from the paragraph given.Narrow down your choice to the option that not only seems to take forward the main idea of the passage but also has the connotation of a closure(Alomost the same logic that we apply to locate the last statement in parajumbles.
All said and done the best way to crack this section is to practice as many questions as possible to identify the grey areas and I am sure you can start experimenting with the tips mentioned here in your MOCKS to overcome the ambiguity of the VERBAL section!!!!

Best of Luck for ALL-INDIA MOCK CATs starting 13th July,2008!

Things that make your day: A testimonial

Below is a mail we received from a former CL student today.


Hello !

I know its late...but really wanted to thank you all for the contribution you have had in shaping my future...d modesty ingrained in teachers normally doesnt allow them to gauge the level of their contribution but sach mein...speaking from the bottom of my heart...had it not been for u all I simply would not have been able to reach dis place.
n its actually not about this place...but about various other traits that i have learned from you that would hold me in good stead in life.

n yea i promise that iss baar will try n study achche se...so that academically bhi i m able to do justice to myself:)

Summers in november...dats d next on target...yahan sab kuch jaldi jaldi karte hain...n haan competition bhi bahot hai coz of relative grading...wing mein ek banda pad raha ho toh baakio ko bhi guilty feel hone lagta hai:( have been trying to resist all this...lets c kab tak !!!

my aim was to make you all feel special and sabki best wishes lene ka...hope dono fulfill honge:)

once again thank you for everything...will keep in touch through mail/phone.
