a of a b ofb 2 of ab then what percentage of a is b options a 50 b 75

hello ...........
a/100*a+b/100*b=2/100*ab
after solving
a^a+b^b=2ab
we can write (a-b)^2==0
this equation is only true whan a=b
so 100% ans

a%of a means= a/100*a = a^2/100
similarly b% of b will be b^2/100
and 2% of ab will be 2ab/100
now putting in d eqn we will get -
a^2+b^2=2ab(100 is eliminated from both sides)
Now, this is the formula of (a-b)^2=0
so that results to a=b .
That means ans in 50% .

sorry in my previous solution that will be 100% not 50% !

assume a and b as100.(100/100)*100=100
same for b
and 100/100*100=100(this is for a is of what % b)
so 100 is the answer

(a^2+b^2)/100=2/100*ab
a^2+b^2-2ab=0
which implies, a-b=0
a=b
ans is 100%

c.. (a-b)^2=0. a=b. a is 100% b.
10 years agoHelpfull: Yes(1) No(0)
from that (a-b)^2=0 so a-b=0 i.e a=b so ans is 100%

ans is -
aa/100+bb/100=2ab/100
so a=b
now ax/100=b
so a=100%

a*a/100+b*b/100=2*ab/100,,, so a^2+b^2-2ab=0,,,(a-b)^2=0,, which can be achieved when a-b=0 that is a=b,, So ans=100%

(a% of a)+ (b% ofb)=2% of ab, then what percentage of a is b? options a)50% b)75% c)100% d) cant be detemined
