@sumit1234567890 how? did u just put d values as 0 1 n -1??
@rajbharati said: if x^2+y^2+z^2 +2 =2(y-z)find x^3+y^3+z^31)02)13)24)3
should be zero...

as x^2+y^2+Z^2 +2 = 2(y-z)
=> x^2 + (y^2-2y+1) + (z^2+2z+1) = 0
=> x^2 + (y-1)^2 + (z+1)^2 = 0 ..... x=0, y=1, z= -1
so
x^3 +y^3 +z^3 = 0 .... Ans
@rajbharati 16k, 24k , 36k
@rajbharati yes by mistake i took z as 1

ans wasnt given but i too got this... by hit n trail method :D

how?

@rajbharati its 0
@rajbharati said: The total earning of A, B and C is 76000 and they have save 30% 25% and 20% resp. If their saving is in ratio 4:5:6. Then wat r d earning of A,B and C.
a=16k
b=24k
c=36k

?

@ansh099 a lot of instead of about

@rajbharati its 0
correct 0
@rajbharati x+Y+Z=76000
now their savings are given
now solve to get ans
He was debarred / to appear / at the examination / NE

also brought...
@rajbharati savings ratio is
30/100x:25/100y:20/100z::4:5:6=k
solve to get the value of x y z in terms of
put these value in X+Y+Z=76000
then u will get ur answer..
