Also plz explain 26 !

[Anjali]

And for 9th its c . Please recheck .
My other answers are all matching with that of yours .

9th of B section

[Arushi :))]

@ anjali..
for 20. refer to pg 220 of hammond. its a harmonic divergent series.
25.
For correlation , we plot the scatter points....
then we see how dense is the plot / how close are points to each other . and also we see the direction ( upward/ downward slope)
so in case of a line its perfect correlation .. 1 and -1.. and in all other cases it lies between them....
ex: if its not dense and still upward sloping .. then its a positive r but less than 1...
26.
the slope of ICs is 16/ 13 = 1.23
and slope of budget line is 13/11 = 1.18
slope of budget line< slope of IC . utility is maximized by consuming only x..

[Anjali]

Thanks arushi ! So you did plotting for this correlation question ?

[Anjali]

Also plz check 9th question of section B !

[Arushi :))]

na , i didnt.. :P
and for 9th i am not sure... need to verify ! maybe you r right

[Anjali]

So how to identify such correlation ?
And also please visit that jnu 2009 doubts page. I have posted a few replies .

[Arushi :))]

@anjali- yup for 9th its c :) my mistake

[kangkan]

Hi ..wats the logic behind question 10..it seems we can apply MC(31)= Tc(31)- TC(30) with TC(30)=20..but are we assuming the AC doesnto change between 30 and 31?

[Ridhika]

Hey guys.. all my answers (Section A only) are matching except 5 and 10

Ans 5) I think it should be (b) preferences, because at any point on the PPF efficiency is already met because all resources are used and so is feasibility. however it is preferences which will determin which of the points on the boundary of the PPF will be produced.

An 10) Between the 2 points (10,10) , (30,10) the TC curve can take any functional form that passes thought these points.. so MC can be anything at q=31

Can someone please explain 13 and 23? I thought 13 was quite simply A..

[The Villain]

23..
7%of x=35
solve this
ans is 500

[Ridhika]

but what about the fact that this bond is giving 35 "in perpetuity" .. doesn't that mean every year recurringly?

[Homer Simpson]

A perpetuity always pays the same amount of interest every year. Ron's calculation is fine.

[Ridhika]

okay.. thanks guys..

arushi in section b
im getting a for the 2nd

and in 8 r=10 (in percentage) so "the value of r" should be 0.1 .. so i think it should be b not d

Can someone please explain b10?

Also my answers to the NIA problem C1 are below, please please confirm as i am not sure,
a) 11500
b) 12000
c) 1000
d) 1000
e)1300
f) how do i get disposable income?

[akanksha]

arushi shouldnt the ans to 9th q be a
bcz... acc. to krugman
 % change i real exchange rate = deviation from relative PPP
                                                = % change in  exchange rate - % change in prices
and also plz tell the ans for 10q
and the natonal income q
thanx alot :)

[Anjali]

@Ridhika how did you calculate part c of NIA ques ?
Iam getting 3200

[mrittik]

let assume the fixed cost c and mc p, TC=c+10p=10....(i) similarly TC=c+30p=20...(ii), solving these 2 eqns we have get the value of p=0.5....so the MC is exactly 0.5....
