can anyone tell me the 4 wrong questions in aieee 2007 please??

even if u know only one tell me

kvenkan

what is the procedure of marking for the wrong questions??

pls ans my first q also

love_hatethatsme

i know abt the definite integral question in which the ans was cumin sec inverse x(one the ans was not there and other the limits were from pi/4 to sumthg, bt pi/4<1;so sq root(pi^2/16-1)is not even defined , it wud give imaginary area), other one was in physics, where there was a confusion of a*r or a/r (a=alpha)

kvenkan

thanks

anybody else ?????

pls help

kvenkan

help please

there was 1 ques of probability whose ans. many istt. has given as 0.14 but actuall answer was 7/22 which was not in option

praveen_ramesh

i think only two ques were wrong, the ones in the first reply
the ques of probability was correct i think. the answer should be 0.14 only
not 7/22

One question of centre of mass in physics was also given wrong by some coaching inst.

i think dat ther r only two wrong quest.

maths- integr. one

phys. - a/r shld b ar in com quest.

remember that difference of roots < root 5 ques. In that... we neglected D > 0 condition... it is necessary for roots to exist... and it wud yield the set (-3,-2]U[2,3)
which was again not in options...

the probability ques was correct indeed.
in ques it was written "in succession" wich means 1 then 2 then again 1 then 2 again 1 then 2 and so on........
by this way and is 7/22
but if we consider 1 then 2 and thats it the ans is .14
since there was no option as 7/22
thus .14 is undoubtedly correct ans.

dfgdf

in one integration where sec inverse was comming and finally ans was sec(3pie/4) i.e. -sqroot2. but none option matched. even fiitjee did not gave any ans.

hey do u think in that integration ques, only this was the mistake that the ans was not matching, i think there was another mistake in the same ques that the curve that was given was not defined in the given interval(ie at pi/4, curve is not defined), and ya, quad ques also, there was sum mistake, had we taken one more conditn

hey tell me if we do not attempt the no answer question will the marks allotted to us?

In chemistry there was a question in which there were two answer-
                Cl₂+NH₃(EXCESS)-------------->NH₄Cl+N_{2
Hence this is the anwers as the equation given is}                Cl₂+NH₃(EXCESS)------------->HCl+N₂
But another anwer is also there as
    Br₂+NaOH------------->NaBr+NaBrO₃+H₂O
