The paper level was moderate although very lenghty.English section was so much time consuming.And was it basic maths , there were questions on circles,diff eqquations.
Any idea what will be the cutoff..

[Akshay Jain]

Acc to dem basic maths means maths upto 12th

and wat abt the the question of type of function- concave ,convex, constant or ....  
function was -e^-x

[SINGHAM]

concave as f''x<0 for all x.

[phelps.phan]

Hey, lets say the function was u(x1,x2)=ln(x1) + x2. So its quasilinear with respect to x1 right?

[The Villain]

yeah x1 is quasi linear

[Anjali]

One more thing. There were two statements :
LM represents causal relation between interest and income
IS represents causal relation between interest and income
What is this causal here ? And are these statements true ?
And one more do CPI , WPI and gdp deflator give same results ? And does gdp deflator account for inflation ?

 it  is quasilear with x2

integration of 1/x^n  from 1 to infinity .(igidr question)
wat would be answer.
i wrote 1/n-1 on the basis of similar question i have solved where n was 4, then answer was 1/3 and when n was5 answer was 1/4

[SINGHAM]

Yes, I also think that ln(x1)+x2 is quasilinear with x2, as it is linear in x2.

[SINGHAM]

There was a condition, hope you will recall, and as you have implicitly taken care off,

n>1.

And, that makes the answer, 1/(n-1), perfectly correct.
