Sir,
in Q18 , paper 1 maths it should only be C,D whereas its given B,C,D.In physics paper 2 Q38 it should A and Q44 match the following , tan(kt)is periodic with pi/k and is not SHM so it should be B,D.

hi bhaiya,
in paper1 maths Q14, shoudnt Statment 2 be false as it says , cos((B-C)/2)>=0.. but if it is equal to zero… then B-C=pie.. how is that possible in a triangle??
yogesh
where can we discuss about the doubtful Qs, in the forums only?
or here?
Sahil Arora
In paper1, que.8, (B)is wrong.
yogesh
following are the Qs, i assume are wrong, please verify
Q4 – A should be changed to B
Q8 – BCD should be changed to CD
Q9 – A,B should be changed to A
Q32 – ACD should be changed to CD
Q46 – C should be changed to B
yogesh
this isnt a valid point.
we can take the limiting triangle to be one with angles A=B=0 and C=pi

bhaiya please post a video sol. 4 ques5,paper1 maths!!
i am not able to understand.

in addition to this i believe ans to ques.59(chem)shoulb be ‘B’.

Physics Paper 1 q34 ans should be [A]
Chemistry Paper 1 q59 ans should be [B]
Maths Paper 1 q8 ans should be [c] and [d]

sir,
In Maths Paper 1
Q4. there is a misprint in the paper. pi is the numerator and 2^tan^-1x -4 is denominator…
if we solve the question by this way, we get ans as (B).
In Physics Paper 1
Q40. the question gives us rms voltage.
so the formula for power is V^2/R and NOT 1/2 V^2/R
thus the correct ans is (A).
In Maths Paper 2
Q20. the options in the solution do not match the ones given in the question.
In Physics Paper 2
Q44. tan(kt)is periodic with period pi/k and also periodic but not simple harmonic.
thus the answer should be D2,D4.
Sahil Arora
Bhaiya ,there is a mistake in sol. of Que.21 part (B) in Paper 2. In sol. there should be 2x-4 in place of 2x-2.
we can check that 3 is not satisfying it. also least Positive integer will be 4 that is not given in option. So answer should be 6.

Bhaiya i think the following answers are wrong.
PAPER-1
Q34
ans. given is B
it should be A
Q 51
no. of forms should be only3 (not4)
I think they are including the iso form of para methoxy benzene but it does not have any benzylli hydrogen. hence it can’t undergo oxidation to give para methoxy benzoic acid.
so coorrect ans. shd. be B but given is C
Q 55
ans. should be ABD BUT GIVEN IS BD
gaurav goel
PAPER 2
Q 10
NO ANS. IS GIVEN
ITS UNCHECKED
Q 21 MATCH THE COLUMN
FOR PART 2 ITS MATCH SHOULD BE WITH 4th option but given is 1st.
Q 35 correct is D but given is A
Shubhranshu
Paper-2 Q.12
reason is wrong as for
f(x)=3mod(x-1)+ mod(x-2) + mod(x-3)
for x=1 f(x)=3
for x=2 f(x)=4
here a=1 b=2 c=3
satisfies a<b0
Shubhranshu
if cosx=0 then,
x=pie/2 not pie
aman
IN paper1 chemistry
ques 62. answer shd be ‘a’ as with the increase in oxidation no. acidic strenth increases. this is also a correct reason for the difference in acidic strength for various acids given.

You gave fantastic honest ideas here. I performed a research on the issue and discovered almost all peoples will agree with your blog.

Considerably, the article is in reality the sweetest on this notable topic.
