The answer to the tv screen question should be 5:6.. As because, if we take same heights for both tv screens, then the ratio of dimensions of the two tv screens would be 12:9 (4:3 multiplied by 3 on both up/down to make the height same with that of 16:9) and 16:9.. And the ratio of diagonals would be- (12^2+9^2)^1/2 / (16^2+9^2)^1/2 = 225^1/2 / 337^1/2 = 15 / 18. something.. = 5/6 (approx)
i think 1st option is correct bcz when thickness increases a maximum volume of oxygen can be absorbed by the surrounding so they can survive in o2 deficient envt
according to me the answer for question 14 will be 4 as you have seen railway tracks though they are parallel,looks converging...so same will be for this case when the columns will be diverging they will look parallel...
cockroach question i nthink the answer is option 2 because when length increases the respiratory organs i.e., spiracles present in lateral sides of the cockroach increase in number therefore enables them to survive in oxygen defficient environment :)
ans for question 15 is not 36 it is 63 bcz taking 9 less than the number means 63-9 =54 and 9 more than the number is 72 54/72=3/4 not 36,45,54 (will not give the answer)
the answer for question 10 is option 3. and not 4 because when you add the volume of hemisphere and cone both with unit radius and height the ans is again π. 3 is the ans because 1,2&4 gives you π while 3 is just an approximate value for π
its should be Answer 3.. becoz there is condition of less oxygen so they should reduce there length that means they need less oxygen to circulate in there body due to less size..but thickness have no role in circulation..

I agree
cockroach question
i nthink the answer is option 2 because when length increases the respiratory organs i.e., spiracles present in lateral sides of the cockroach increase in number therefore enables them to survive in oxygen defficient environment :)
but i have a doubt...about the word "compromise" in the question .does it mean making the cockroach more efficient or less efficient.
Mam answer for question no 7 is coming 120.that is option a.and thanks for the explanation.
mam please u solve question no. 13 part A TV screen wala question if possible.
ans for question 15 is not 36 it is 63
bcz taking 9 less than the number means 63-9 =54 and 9 more than the number is 72
54/72=3/4
not 36,45,54 (will not give the answer)
Many of your answers don't match with the answer key provided in the website...!?
question number 9, regarding TV, in CSIR answer key it given as 5:6madam
The ans of Q15 is 63 ,that is option 2. the number is 10x+y
N/D= 10x+y-9/10x+y+9=3/4
or, 40x-30x+4y-3y=63
or, 10x+y =63(where,x+y=9)
Mam can you please give the part A solution of past ten years of csir NET?
question 10, the odd they gave is 22/7 madam..in answer key !!
Thank you...we need Part-B&C also
The answer to question no.15 should be option 2.
proud to be your student miss ☺☺☺☺
Q14 ans is 3 bcs all columns have equals size
Thanks Ma'am very much for your nice explanation...been looking for it...
question 8, answer according to CSIR booklet is 3.
the answer for question no; 10 is 22/7.....because all the rest are "pi"
These question is not including under life science
The answer of question 4 is 'a' option
By solving the Q.9 we get 5:15 not 5:18.
ans. of 8 is opt. 3
Which set A ,B or C ?
Thank you mam
Thanks
Madam please hindi and English reading ( mix )
