thanx prawez

can u please mail set a question paper so that i can match the answers with set c

there is sm variet

there is sm variety in key’s, but thnx dosto

plz upload physical science key paper of CSIR/NET dated 18/12/2011….along with a question paper…

r else suggest me wher i can find it

In set A….

3rd question, about mathematical manipulation isnt the step

x= 5 being written as X2- 25= x – 5 wrong

so the answer shud be

1, step (i) to (ii)

but in every answer key its answer (4) iv to (V)

please correct me if i am wrong

can you elaborate it plz, i m not getting what you said.

you are wrong dude. problem is wrong if we cancel (x – 5) on both sides , as it is zero

hint: ab = ac implies b=c provided a not equal to zero.

will you send me the key ans for SET-C ??????

chemical science paper very easy so ansers provide in web site

sir/madam

i need key mathematics

plz send me if u have

plz give me answer key physical science set-b

will you upload chemical sciences key

hi i am sorry that my query wasnt clear enough for you to understand

Lemme try again

Question 3 Set A

See the following mathematical manipulations

(i) Let x= 5

(ii) then x2 – 25 = x-5

(iii) (x-5)(x=5) = x-5

(iv)x+5= 1 (cancelling (x-5) from both side

(v) 10 = 1 (putting x= 5)

which of the above is wrong step

1) (i) to (ii)

2) (ii) to (iii)

3) iii to iv

4) (iv) to (v)

shouldnt the right answer be

1 (i) to (ii)

rather than 4 (iv) to (v)

because you can never write x= 5

as x2- 25 = x-5

your answer is correct

you are wrong dude. problem is wrong if we cancel (x – 5) on both sides , as it is zero

hint: ab = ac implies b=c provided a not equal to zero.

Please upload the answer key for earth sciences

is it correct answers ,,it is not matching with jodhpur answers

(i) x=5

(ii) x2-25=x-5

(iii) (x-5)(x+5)=(x-5)

(iv)

ans- (ii) to (iii) is it right?

can answer keys of maths science be made available?

i agree wid u neems…even i hv checked first option…

anyone know earth sci set A answer key

can you please provide question paper for set B of chemical sciences

the mathematical manipulation is quite confusable.

when x=5,then it should be X2-25=0. how it can be X2-25=x-5.

otherwise ‘x’ value should not be given, if the aim is to find ‘x’ value from the given derivation x2-25=x-5. if you do so, the derivation will be

x2-25=x-5

(x-5)(x+5)=x-5

x+5=1 (by cancelling x-5 on both the sides)

x=1-5

x=-4

the given value of ‘x’ is not matching the value obtained from solving the derivation. the logic behind this question is not clear enough

for Q12 in part-A according to me answer 1 can be correct. because a single cube itself can submerge 20% without any object over it. when we place similar cube with capacity to submerge 20%,already existing cube need additionally 80% submerging capacity to submerge completely.it can be achieved if 4cubes placed over existing cube.

for question no 84 in B pattern,the answer can be [1]0.375.

because,

no of children for the given parent is=3

possibility of male/female child is1:1

s=[ MMM, MMF, MFM, FMM, FFM, FMF, MFF, FFF ]

n(s)=8

n(MMM)=1

n(FFF)=1

n(MMF)=3

n(FFM)=3

possibility of two daughters and one son=n(FFM)/n(s)

=3/8

=0.375

Q92 in pattern

5′TACCGTGGACTTGA3′ [WILD TYPE]

5′TACCGTG ACTTGAG3′ (MUTANT TYPE)

DUE TO DELETION OF ‘G’ FROM THE WILD TYPE , READING FRAME IS SHIFTED.

HERE TRANSITION/ TRANSVERSION IS NOT POSSIBLE SINCE IT IS DELETION , NOT SUBSTITUTION

HENCE IT CAN BE ‘FRAME SHIFT MUTATION’

in set a maths key 61 question answer is 1.bcz if kth partial sum is 0 then the infinite sum is 0.Q-70 answer is 2,3 bcz one ofthe eigen value is 0 and remaining are positive so it is semi positive definite and the eigen values are different so it is diagonalize.

in Q-71 rank is 2 and 0 is an eigen value of A answer is 2,3

any one discus withe me we find correct answers….

well for set B, life Sc, q. 5 should be option 4, because…

x +5=1

so, X= 1-5

x=-4. but as given , x should be =5, so here -4 is nt equal to 5 . In addition there is no right or wrong in the option 1 as here only the value of x is given.

again in the q.12, u cant directly say tht it wil b 4 because it is nt mentioned anywhr tht the cubes r of equal size or weight…so i think it will be infinity i.e. the option 4.

pls send me csir net earth science 2011 december keys of set c to yoratnamus@gmail.com

the 1,2 and 3 steps have no mistakes. but the 4th step is wrong since division with zero is not possible ( here x=5 means x-5=0 and cancelling from both sides means dividing with x-5). hence the steps 4 and 5 is wrong. thus the answer is 4th option.
