JEE Numerical Pattern doubt
if a questions has answer lets say 769.5 and its hard calculation so will our ans only be correct if we write 770 or even 769 will be correct , so what i am asking is , is only 1 exact ans correct for questions with very hard and lenghty calculation?

idek who to ping
chem has worst calc so ig them
@Dexter
Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.lmao
Yes ig.
i dont know but its accepted everywhere to round off .5 to 1
and if i were to guess, only 1 answer accepted yes
I remember one time I got the answer as 76.2 in chem while it was 76.6.
i despise physical chem calculations
can you imagine having to do this division accurately
For physical chem, try not to take much approximation ig
correction
take NO approximation
i aint even kidding
rounding off 114.392 to 114 in that solution
gives a different answer
Ah they should have a slim range for that.
But NTAs will be NTAs.
😭
advanced me range hota hai
for all this rot
actually?
jee main ka maloom nahi tbh
bro mains ko zyada zarurat hai
never seen ranged answers for pchem so im gonna assume not
advanced me literally 1 sig fig ka range hota hai
depending on the calc, if it ihas log or not
holy shit 😭
(like the kinetics one from last year)
check solutions of advanced from 2024.
most have range where necessary
again - main dunno
sometimes i wish only advanced existed
no mains
Niice
we'd have a country more full of actual critical thinkers
Matlab advance mein approximation is okay?
1 sig fig ka range hai
usme jo krna hai krlo
and if advanced has a range im guessing they account for common approximations
Wait so ek significant figure ka matlab 76.4 hai toh 76.3-76.5-ish something?
like turning 114.392 --> 114
i think so yeah
damn that doesnt look enough actually
nah thats foul , this guys sometimes dont even give value of root and expect us to get accurate answer
Fr.
yeah
But tbf karna hai toh karna hai.
But when the first introduced numerical range ques
they gave huge ranges lmao
pick up 2017 advanced ka paper and uski answer key
but do we put decimal or always round off
bhai agar you're getting 769.5
then just divide for one more decimal place just to be sure
if its like 769.56
then go for 770
if its dot 769.5
depends
itna socho mat
then idk dude
do your thing properly bas
Oh those are nice ranges.
it depends :D
on the q
i was asking for jee mains
AGAIN this is adcanced
haha yes
on the calculations ig
Ah I see.
mains dunno :O
do they allow range in any question?
135 to 151 wallah 🙏
mains mein they give range if bohot controversy hoti hai
nahi to naw
and not even range
like if your answer is
769.5
and you fill 770
and alot of people have filled 770
then they'll give 769.5 and 770 as the answer
no range
i imagine calculative physical chem questions have like a 9:1 wrong to correct ratio
two answers
na
imma closing this.
post on advice or continue this convo on general xD
Bhai Thermo kinetics and electrochem anti logs are craxy
+👍
