"The statesman who should attempt to direct private people in what manner they ought to employ their capitals would not only load himself with most unnecessary attention but assume an authority which could safely be trusted to no council and senate whatever, and which would nowhere be so dangerous as in the hands of man who have folly and presumption enough to fancy himself fit to exercise it."

This was the XAT 2011 essay...........
Can any1 explain me what it asked xactly???

spiritofmars Says

It's an excerpt from Adam Smith's Wealth of Nations, if I remember correctly. You need to present your views on the statement. You can talk about the consequences of license raj in India, deregulation in 1991-92, abuse of economic power by citing multiple examples of corruption & misuse of authority... there are multiple approaches.

I think the excerpt has been nicely put in other words by spiritofmars...
My take on such kind of essay writing would be either u go against it or for it...give 2 to 3 examples with 2 to 3 facts...

well let me explain with small illustration you see petrol/deisel prices rising randomly irrespective of stable international prices still here at national there is volatility in oil prices.all due to government has given free hand to ONGC,IOC an dother private players to manipulate prices for their profits.result you can see by yourself due to rising pricves in oil it has immediately affected torise in prices in cereals,vegetables,fruits,dry fruits.

i think the topic implies to Totalitarianism or a totalitarian leader (like kim jong ll).....

XAT 2005
The demand for a product (Q) is related to the price (P)
of the product as follows:
Q = 100 2P
The cost (C) of manufacturing the product is related to
the quantity produced in the following manner:
C = Q2 16Q + 2000
As of now the corporate profit tax rate is zero. But the
Government of India is thinking of imposing 25% tax on the
profit of the company.
38. As of now, what is the profit-maximizing output?
(A) 22 (B) 21.5
(C) 20 (D) 19
39. If the government imposes the 25% corporate profit
tax, then what will be the profit maximizing output?
(A) 16.5 (B) 16.125
(C) 15 (D) None of the above


Plz help

Below is the solution:

Q=100-2P
Hence, P=/2(100-Q) where P stands for the price
Cost , C = Q^2-16Q+2000
The profit= Revenue - Cost = > Revenue =P*C = Q*(100-Q)/2 = (100Q-Q^2)/2
Profit = [ (100Q-Q^2)/2-(Q^2-16Q+2000)]
= [100Q-(3*Q^2)+32Q-4000]/2
= [132Q-(3*Q^2)-4000]/2
For Profit to be maximum or minimum, we need to calculate the first differential
dP/dQ= 132-6Q = 0
=> Q=132/6 = 22

That answers your first question

3 A

Now , for next question, since the govt is imposing tax on the profit and not the output, hence, output remains unchanged

39) D since, non of the options is 22

thanks a lot it indeed is very beneficial

Well, you will need to surf around - I doubt you can find a tailor made essay to this particular statement. That being said, you can easily get a huge amount of material on this topic on blogs. You can even take a contrarian stand and argue that the multiple failures of the economic system indicate some amount of regulation is necessary & one cannot let capital deployment be solely a matter of individual choosing.

Really, the best guide is you & your thought process - you will be convincing & eloquent if you are arguing for your own opinions.

just making a wild guess. is th answer 1:1??
thought the figure is not symm. but hunch hai. :p

for solving a parabola u need to know higher maths...this question requires use of integration...a basic formula of integration
integration of x^n=x^n+1/n+1
in this question u have to integrate it upon x axis....first by solving the equation
the 2 parabolas meet at 1/2,1
the area of the triangle formed is 1/4.integrating the first parabolic exuation we get 4x^3/3
integrating second we get root2(2/3)x^3/2.put 1/2 in these 2 equations we get 1/6 and1/3.now subtract area of traingle from 1/3 and 1/6.taking mode of the two(as area cant be negative) and dividing them we get 1:1 ratio.....

Puys I just saw a couple of Para based questions in XAT 2005(hard copy). The questions and the choices given are so irritating and turning me mad. I cannot even call it difficult, but its way beyond it.
If some one has the soft copy of XAT 2005 papers plz copy paste the para based questions on taxonomy
the one on "concept.."
Lets discuss the questions

I have the proper ebook version of Critical reasoning bible. (arnd 1.4 mb).
PM me your mail ID and I will send it across.

hi,
i hv sent my mail id to u...waiting for ur Ebook...

hey, plz send me that ebook...

Dude posting ur mail id is against PG rule. Please PM it.

Will check it from some other source and confirm !!

Yeah me too came across the same prob in one mocks, the explanation is not clear. Option a-d is not fitting.
However, I will suggest one link for a typical problem. manisha's problem reminded me of that-

can anyone suggest me any ebook for LR????

manoj1986 Says

the key is probably incorrect.

Will check it from some other source and confirm !!

let me clear what i hv got as solution..

let A make 2,,,
(after this whatever B makes A has to make this pair equal to 11)

therefore 2+11+11+11+(here comes the winning move,,it is B's turn whatever he choose A ll make it to 46)

hope m clear..

correct me if m wrong :)

Had (b) been the correct option, your logic would have sufficed but I fail to understand and fir in ur logic with 4 as the starting move for A

dont know, I still think there is something wrong with the question. It doesnt clearly mention anything about same number/different numbers. moreover, options are like A must start with 2,4 so on but not "A must select/choose 4"

Iteration 1:
A chooses 2 ,B chooses 9 (suppose) total =11
Iteration 2:
A again chooses 2 , B chooses 8 | total = 21
Iteration 3 :
A chooses 3 this time , B chooses 9 | total = 33
Iteration 4 :
A chooses 1 this time , B doesn total = 35
Iteration 5 :
Now no matter what A chooses, B will win the game

Hey, i agree with the 35 but what is the trick when one backtracks from 35 to 24 or 15? Please share the logic.

Actually it is like,
46-(10+1) = 35 needed
35 - 11 = 24 needed
24 - 11 = 13 needed
13 - 11 = 2 needed



..............................................

manoj1986 Says

oh I tought A can choose different numbers in different iterations

Dats what...One needs to nail the backtracking knowledge to arrive at 4 as the answer!

chugh.manisha Says

OA is option (d) A starts with 4

oh I tought A can choose different numbers in different iterations

Two players A and B play the following game .A selects an integer from 1 to 10 , inclusive of both. B then adds any positive integer from 1 to 10 , both inclusive , to the number selected by A.The player who reaches 46 first wins the game.If the game is played properly, A may win the game if:

a) A selects 8 to begin with
b) A selects 2 to begin with
c) A selects any number greater than 5
d) A selects 4 to begin with
e) None of the above

OA is option (d) A starts with 4

if A select 2 then B will play intelligently and make 4..after that it wud be imposible for A to win.
coz after 4 B will make 15 and then 35

A-2,B-4,A-7,B-x,A-11-x
I dont see A losing, can you provide the entire path? assuming A plays well and chooses 11-the number chosen by B

manoj1986 Says

I think b is correct too, can you give ma counter example to prove b wrong..oops intended for sujamait

Iteration 1:
A chooses 2 ,B chooses 9 (suppose) total =11
Iteration 2:
A again chooses 2 , B chooses 8 | total = 21

Manisha.. firstly this ques was a bit incomplete.. btw ratios of roots of both eqn were equal was implicit..
sol) equate ratios of both eqn
apply C and D
squaring both sides
DONE :)

Hey, this was straight from one of the mock test with nothing per my knwledge missing. But, yes implicit assumption is required to solve it.

That's correct!! U r such a rockstar I must say Can you please xplain this one ?

Manisha.. firstly this ques was a bit incomplete.. btw ratios of roots of both eqn were equal was implicit..
sol) equate ratios of both eqn
apply C and D
squaring both sides
DONE

chugh.manisha Says

If I go by your logic, shouldn't d be 10 and not 20?

no in first case roots are 5,1 ratio is 5
in second case roots are 10,2 ratio is 5
(x-2)(x-10)= x^2-12x+20

chugh.manisha Says

That's correct!! U r such a rockstar I must say Can you please xplain this one ?

let the roots of the 1st eqn. be p and q

p+q=2a
pq=b

(p+q)^2=4a^2 divide this by pq=b

do the same with the 2nd equation

and solve...

one way to solve is by example.
x^2-6x+5=0 and x^2-12x+20=0
a=3,b=5,c=6,d=20
comparing the options, you can see that c is right

If I go by your logic, shouldn't d be 10 and not 20?

If the ratio of roots of the equation x^2-2ax+b=0 is equal to x^2-2cx+d=0 ,then
a)(a^2)*b = (c^2)*d
b)(a^2)*c = (b^2)*d
c)(a^2)*d = (c^2)*b
d)(d^2)*b = (c^2)*a
e)None of these

My take...

If the ratio of roots of the equation x^2-2ax+b=0 is equal to x^2-2cx+d=0 ,then
a)(a^2)*b = (c^2)*d
b)(a^2)*c = (b^2)*d
c)(a^2)*d = (c^2)*b
d)(d^2)*b = (c^2)*a
e)None of these

is it ratio of roots of eq1 equals ratio of roots of eq2 ? i didn get it.
if yes then option C

my take in bold!!!

That's correct!! U r such a rockstar I must say Can you please xplain this one ?

If the ratio of roots of the equation x^2-2ax+b=0 is equal to x^2-2cx+d=0 ,then
a)(a^2)*b = (c^2)*d
b)(a^2)*c = (b^2)*d
c)(a^2)*d = (c^2)*b
d)(d^2)*b = (c^2)*a
e)None of these

one way to solve is by example.
x^2-6x+5=0 and x^2-12x+20=0
a=3,b=5,c=6,d=20
comparing the options, you can see that c is right
