GDP fc=10,000
NFIA=500
Net indirect taxes=1500
govt non-investment expenditure at market price=1500
current a/c deficit on bop=500
gross savings of govt=-300

q.1.if pvt consumption expenditure is 0.75 times the GNP at market price,calculate  gross investment.
2.calculate gross savings & gross pvt savings in economy.





Q2.suppose aggregate income in an economy = total wages+profits.40% of all profits are saved.if the share of wages in aggregate income is 60% and the rate of saving in the economy is 0.25,what is the fraction of wages saved in the economy?


Q3.  year       X-M     G-T     S-I

       2005     150                150
       2006                -50      -130
       2007     -200     345

find missing values in table?( 0,-80,145)right ya wrong?



Q4.if x,y are real numbers and it is known that x.y<2,then it must be that
a.x,y are both less than 2
b.x,y are both positive
c.atleast one of x and y is positive
d.atleast one of x and y <2(right answer acc to me is last)



Q5.suppose n observations of a variable yield n different values with median m.suppose the observations with maximum value and the minimum value are omitted.the median of the remaining n-2 obsn is
a.>m
b.<=m
c.<m
d.none of above



Q6.A uses his salary of 2 lakh a month to buy shares to earn dividend.B borrows 2 lakh from bank to buy a new machine  for business.C deposits his salary of 2 lakh in bank a/c to earn interest...in macroeco,actions of A,B nd C are characterised respectively as
A.inv,inv,saving
B.inv,inv,inv
C.saving,inv,saving
D. inv,saving,inv

Q3 answer is perfect. Will get to the rest soon!

Q2.suppose aggregate income in an economy = total wages+profits.40% of all profits are saved.if the share of wages in aggregate income is 60% and the rate of saving in the economy is 0.25,what is the fraction of wages saved in the economy?

wages share= .60
profit share = .40

rate of saving = .25 = wage saved + profit saved
.25 = .60*x + .40*.40
x= 15% of wages are saved

Is this one of the options...

[Badmathsboy]

you are right for q.4... For q.5 > Median should not change at all, so take your pick > either option b or d?? I am confused.. :/

[anon_econ]

haha.i think it would be d. these guys dint make up the options correctly.
ritu the median does not change bcoz if half the values were greater than m earlier, half of them would be greater than m even after u remove one obs from each side of m.

[aditi5000]

Yeah definitely D. It's their attempt to confuse us, but an inequality is surely not the same as a strict equality naa.. stick to D.

6. (c)

[aditi5000]

yes I agree with Chocolate frog - 6.C

@Badmathsboy

the answer for the median one is d, this is so because the extreme values do not have any impact on the median

[Ankit Agrawal]

I guess the answer to the 5th question is b.

In case there are odd number of observations, then the median remains the same.

In case there are even number of observations, the median CHANGES. How?

Let's assume that there are 6 observations. The median would be the average of the THIRD and the FOURTH observation. But if we remove the first and the sixth observation from consideration, the new median would be the average of the SECOND and the THIRD observation. It is known that, while calculating the median, observations are arranged in the ascending order. Hence the second observation will be smaller than the fourth observation.

Ergo, the median will be <=m
