net lump sum tax revenues result in full employment output?
(a) A Rs 20 decrease
(b) A Rs 20 increase
(c) A Rs 16 increase
(d) A Rs 16 decrease

Ans - (c)

I want to know if I did them correct  :(

[MohitG]

Hey guys plzz reply

[SoniaKapoor]

q22 and 23 ...my answers are same as yours

[Anjali]

Hey ! For 19 , I think its c .
Change in Y / change in G = 1/1-c
80/change in G = 5
Change in G is 16 . Since output has to be increased , G should be increased.

[Anjali]

And fir 22 and 23 , my ans are coming to be the same as yours.

[MohitG]

Thank you Anjali and Sonia :)

[econ14]

anjali for 19 why (c) not (a) plzzzz help.

[ViV]

19 (a)
22 (c)
23 (b)

[Shefali]

pls explain quest 19

[ViV]

lump-sum tax multiplier
dy/dt = -b/1-b
80/dt = -0.8/0.2
dt = -20

Has somebody done QUES 24 of this paper. Please reply? Thanks

[Aish]

Can someone please tell how to solve 9 11 and 12. please :(

[ViV]

9
Area = Integrate(x+4)dx from(-6 to 0) + Integrate(x^2)dx from(0 to 5) + Integrate(7dx) from(5 to 8)
      = 206/3
12
Probability = Integrate(x)dx from(1/3 to 1) + Integrate(2-x)dx from(1 to 5/3)
              8/9
Similarly, Integrate(2-x)dx from(1 to 2)
probability = 1/2

I couldn't do 11.

[Dreyfus]

 for q11

[ViV]

THANKS vaibhav

[Aish]

Thanks a ton Viv and Vaibhav :)

Consider in country A incomes are 50,60 nd 70
avg is 60
in country B are  30,40 nd 50
avg is 40
now the person vd income 50 from country A moves to B
new avg in country A is 65
and in B is 42.5
thus both avgs increases
so it cannot b option A

[ViV]

So Akshay what should be the Answer for this question??

[Akshay Jain]

according to me it shud b option D...

[ViV]

But I am getting C as I worked with an example.
