it was a perfectly right solution set this time for class 10th published by unified council.... ntse blog people , learn something from them how to make an answer key ... take time but publish a correct answer rather than publishing an answer key full of errors.. it s a way to demorlaise students by producing wrong answer keys.. please look into it next time.

for class 9th answer key--- ques 10 and 25 's answer in the ANSWER KEY is 100 percent wrong

Benedict said...

In Class 9 answer Key :
10) Since P^4+P^2=20 --> P^4 + P^2-20=0
P^2-4 (P^2+5)=0 and p is an integer --> p^2=4 p=2,-2.
The sum of the 2 integral values which satisfies p = 2+ (-2) = 0 The solution is right but the answer is marked as D which is actually C

25) It is 1+2012 times i.e., 2013 times. It is not 2012 times.

@ 1st comment, 2 questions of class 10th NSTSE ARE WRONG
q49 & q62....take your time in reviewing the questions and keys....dont misguide the students that unified council is perfect..!!

@ 4th commenter ; q.no 49 just checked our knowledge that v1=v2 and v3=v4 , there is no stipulated calculataions. and please say what is wrong in 62nd question? Subject experts itself have said there is no wrong in that question. How did you find a mistake in it !???! If you dont know the answer , dont say the question is wrong;

For class 10 Q62 is correct....what's wrong????
and in Q49 the voltages V1 and V2 definitely can't be 3V as the total voltage provided by battery is 3V so how can the V across 1 bulb be 3V???? There is no correct option in the question paper....

Class 10th ...Q97)Amethyst is also colourless in pure form and can be mistaken for a diamond....answer should be B and C....
Q7) Its nowhere mentioned that the marble is placed vertically...so can't it be placed horizontally also?? It should be mentioned or a figure should be given bcoz that way the answer is (15*root 3),so this question should be bonus along with Q49....
How many marks are you ppl getting???????

class 10 in q 49,V1=1.5 V ,V2=1.5V, V3=1.5 V, V4=3 V
PLEASE DO SOME CALCULATION


q 62...HYDROGEN IS NOT A PRODUCT.
conc. of Na+ ions is much greater.
products are Na (which combines with H2O to form NaOH) and Cl2
therefore..
X->H2
Y->chloralkali
Z->NaOH (at cathode)
W->Cl2 (at anode)

option (A) cannot be d ans..
...it decomposes to form NaOH .....products H2 and Cl2 ??
are u kidding me...??
it will decompose into Na+ IONS
which will be discharged at cathode forming NaOH as 1 of the products

thus the options are wrong..it should be (B) with Z and X reversed.... :P:P

@Benedict ur right 10th and 25th answers should be changed..... plz unified council.. take action on these questions

CLASS 10
@ 13 anonymous....
Q62.)You can check NCERT for conformation... the answer is correct... NaOH is one of the products....H2 and Cl2 are released at cathode and anode respectively...
The name of process is chlor-alkali bcoz chlorine is also a product...

Class 10, Ya please check out the NCERT... Page no.30. Before saying anything, please have some knowledge.. First of all be strong with your NCERT's before studying chapters like equilibirum. :/ As if you are the one who know everything , you are saying it right... ! :P :P

to quote the idiot


" @ 4th commenter ; q.no 49 just checked our knowledge that v1=v2 and v3=v4 , there is no stipulated calculataions. "

class 10 q49....
1st circuit...total voltage is 3V ...
each bulb will have 3/2=1.5V
*V1=1.5 V*
2nd circuit is exactly the same
*V2=1.5 V*
3rd circuit..total voltage is 1.5 V
*V3=1.5 V*
4th circuit ..total voltage is 3 V
*V4=3 V*
OPTIONS ARE WRONG ..U CHUCKLEHEAD

as said by the 4th commenter...

DO SOME CALCULATION..!!

@4th commenter ...q62 is right..

Anonymous said...

you may be an idiot who said a completely right question as wrong. you may be a dumb headed , chuckleheaded fool. i atleast supported a question using mere concept that v1=v2 nd v3=v4 ... You didnt even have an appropriate reason to support ur answer of 62nd question. so please mind your tongue before saying anything.

NO CHANGE IN ANSWER KEY OF CLASS 10!!!Q49 should b bonus....

Anonymous said...

U R ABSOLUTELY RIGHT.....IDIOTS

Anonymous said...

Even if you say that V1=V2 and *V3=V4* there is no such option.... so still the question is wrong.....

Anonymous said...

WOW...!!!....SUCH A NICE CONCEPT .....BUT FOR FOOLS ONLY... AND Y THE WAY V3 IS NOT EQUAL TO V4 ANYWAYS
*FOOL*

"@4th commenter ...q62 is right.."

Anonymous said...

Can you prove...V3=V4?????????
Please you people stop using that abusive language...Only you 2 are not using the blog......
