@Brooklyn is dere any way to change my post preference...??
yar i have no idea!! sry
@mickym said: a/(1-a) + b/(1-b)+ c/(1-c) = 1
then find
1/(1-a) + 1/(1-b) + 1/(1-c)
4
abhi iska ek method strike kiya hai
in case you do in this way kindly ignore it

now we see we need 3 numbers whose sum is 1
so equate any one of them
a/(1-a)=1/3
so a=1/4
now put that in the other equation

nopes...this year it won't b possible

@gudda1122 : i used a=b=0 n c=1/2

bhai aise mein hamesha easy experiment karne se bachna chaiye
because suppose kare
yhaan answer kuch aur form mein hota
then aapko 1 more experiment karna padta
and time lag jata
kindly tell logic too....because answer is not known

Sare cos ko sin ke form me lake expand kar do 2nd eqn ko
ho jayega
use Sin^2+Cos^2=1
@hellodelhi said: kindly tell logic too....because answer is not known
ans is known 3:1 :)

@mickym said: a/(1-a) + b/(1-b)+ c/(1-c) = 1
then find
1/(1-a) + 1/(1-b) + 1/(1-c)
4 ??
@hellodelhi said: kindly tell logic too....because answer is not known
bhai 3:1

AG= 2/3 AD
AO= 1/2 AD

So AG = AO + OG
=> OG= 1/6 AD

So AO:OG= 3:1

4 ??
(a+1-1) / 1-a .. ais ekarke separate kar lo ... -1 + 1/(1-a) ajayega.. similarly for b and c.. so -3 ko rhs pe le jao to 4 ajayega

goin for lunch

suppose kare agar answer de rakha hota (a+15/4)

then aapki value se yeh answer nahi aata
but correct answer yeh hi h

actually kuch example aaya nhi dimag mein isliye yeh likh diya

kuch aur question kai kya?????

yaar there's no way to do this. last year tak to yahi tha. agar fir bhi koi confusion hai to ssc chief ko tweet kar do.
