84. Following are given
(i) All P are Q.
(ii) No Q is R.
From (i) and (ii) we can infer that
(a) some P are R
(b) no P is R
(c) all P are R
(d) None of the above

85. Following are given :
(i)
Some P are Q.
(ii) No R is Q.
From (i) and (ii) we can infer that
(a) some P are R
(b) no P is R
(c) all P are R
(d) None of the above

[Dreyfus]

For 84th..i think it should be no P is R....because All P are Q means P is contained in Q and no Q is R means Any of the P can'tbe R so it should be b)

84. Following are given
(i) All P are Q.
(ii) No Q is R.
From (i) and (ii) we can infer that
(a) some P are R
(b) no P is R
(c) all P are R
(d) None of the above

Proof: Statement (i) says that P is a subset of Q.
Statement (ii) says that Q is a subset of R-complement.
Thus, P is a subset of R-complement.
Alternatively,
Story Proof: Let P be the set of people who are good at probability. Let Q be the set of people who have good quantitative skills. Let R be the set of people who are retarded. Clearly, no person who is good at probability is retarded.
Hence, no P is R.

85. Following are given :
(i) Some P are Q.
(ii) No R is Q.
From (i) and (ii) we can infer that
(a) some P are R
(b) no P is R
(c) all P are R
(d) None of the above

Proof: Statement (i) says that P ∩ Q is non empty.
Statement (ii) says that R is a subset of Q-complement.
Clearly none of (a), (b) and (c) can be inferred.
For example:
Example 1: P = {1, 2, 3}, Q = {3, 4, 5}, R = {6, 7, 8} rules out (a) and (c)
Example 2: P = {1, 2, 3}, Q = {3, 4, 5}, R = {1, 6, 7, 8} rules out (b) and (c)

Hi everyone. I'm having difficulty in solving the below questions. I do not have an economics background, so any help would be appreciated

Q.25 JNU 2013
India's GDP in 2009-10 at 5000000 crore. Indians working abroad remit to the country 150 crore and foreigners working in India remit 100 crore out of the country. Foreign investors repatriate 50 crore and Indian businesses abroad bring in 10 crore. India's GNP in 2009-10 would have been

a) 5000050
b) 4999950
c) 5000090
d) 4999910

Sol.       GNP = 5000000+150-100-50+10 = 5000010

What is incorrect in the above solution?

Q. 26 JNU 2013
National Accounts of a country show the following

NFIA                                                 10
Income from private domestic industries 780
Income from governmental industries     100
Personal consumption expenditures        500
Government Purchases                        250
Exports                                             40
Imports                                             60
Depreciation                                       30
Then the net domestic product is

a) 890
b) 880
c) 910
d) 660



Q. 60 JNU 2013
The GDP of a country is growing at 5%, its population growth is 2% and its income elasticity for food is 0.5. We can expect food demand to grow at

a) 2.0
b) 2.5
c) 3.5
d) 5.0

How would this be solved?

[suvidya patel]

5000000+150-100
5000050

[suvidya patel]

not sure bt
income elasicity=.5
ie change in cons/change in income=.5
therefoe change in consumption =.5*change in income
                                            .5*5%
                                           =2.5%

Thanks a lot suvidya...

THanx a lot Sir

Q.25 the investment term already included GDP (whether it is by domestically or by FDI), now we need only GNP=GDP+Net Factor Income from Aboard=5000000+150-100=5000050.

Q26. We have to do this by Income Side calculation where only net GDP is calculated = Income from private domestic industries + Income from governmental industries = 780+100=880. No depreciation is added because it is mentioned only NET.
