SAU PAPER

[Homer Simpson]

Jack, for 48, I am guessing its like this-

take AVC = 82 - 6q + 0.2q^2

Then after using the first and second order derivatives, we see it reaches minimum point at q = 15

Since the AVC function is u-shaped, then for q>15, AVC must be rising. Thus we can take q=25 (highest possible q value mentioned)

Is it correct? Also, how to do 40, 41 and 44?

Q44
Y=k^0.4*L^.6
take log both side, we get
log Y=.4logK+.6logL
then differentiate
d(logy)=.4d(logK)+.6d(logL)
we know that growth rate of capital=8
growth rate of labor=2
put these value in the equation
So
d(logY)=0.4*8+.6*2
3.2+1.2
4.4
so option A

[Homer Simpson]

Thanks. Could you try out these macro problems please?

Plz anyone post the solutions with explanations for the following questions of SAU 36,37,39,40,44,45.

[Ashima]

Someone please tell me the answer for 10th. Should be d.

Because as per the statement "b" should be zero

and thus LM should be unaffected.

[Economics student]

37th is simple.

S1 / S0 = (1 + Iy) ÷ (1 + Ix)

Where,
S0 is the spot exchange rate at the beginning of the time period (measured as the "y" country price of one unit of currency x)
S1 is the spot exchange rate at the end of the time period.
Iy is the expected annualized inflation rate for country y, which is considered to be the foreign country.
Ix is the expected annualized inflation rate for country x, which is considered to be the domestic country.

Use this, you will get.

44th

Y=k^0.4*L^.6
take log both side, we get
log Y=.4logK+.6logL
then differentiate
d(logy)=.4d(logK)+.6d(logL)
we know that growth rate of capital=8
growth rate of labor=2
put these value in the equation
So
d(logY)=0.4*8+.6*2
3.2+1.2
4.4


45th

2.33 Sample variance, so you take n-1 in denominator.

Rest even I dont know.

@sonia In ques 44 , what is the difference between growth rate of output and growth rate accounted for by factor accumulation ?
And we are differentiating the function with respect to what ?

[Economics student]

Total differentiation.

[Homer Simpson]

or you can take the log and differentiate with respect to time, thereby giving you growth rates

@tsuki In ques 44 , what is the difference between growth rate of output and growth rate accounted for by factor accumulation ?

Please explain to me Q.numbers 27 and 28, i.e the football-swimming sum and the weekend-trip sum

[SoniaKapoor]

Who all have their centres at kendriya vidyalya ,ber sarai?

[anishagulati]

Can you please confirm q4, 22, 30?

[arohigupta]

please forward the answers of  sau question paper 2013


thankyou

[arohigupta]

If investment is not dependent on interest rate, the slope of the LM curve would bd
(a) zero
(b) infinity
(c) negative
(d) unaffected

[The Villain]

ans is d

[Anjali]

My centre is at KV Ber Sarai. I suppose maximum people would be having their paper there.

[Anjali]

Any answer for ques 41 ?

[AnonymousNow]

@ron Please explain me q.30 plz
