Read Solution (Total 10)
-
- given
13 = 13w/(1-w)
or 1=w/1-w
or 1-w=w
or 2w=1
so (2w)2=1*2=2 - 11 years agoHelpfull: Yes(33) No(1)
- i doubt that its a tcs question...it just cant be

- 13=13w/(1-w)
13(1-w)=13w
13-13w=13w
13=26w
w=13/26
w=1/2
then 2(1/2)*2=2
Ans.D - 11 years agoHelpfull: Yes(2) No(0)
- 13=13/1-w
13-13w=13w
23w=13
W=1/2
(2w)2=2 - 11 years agoHelpfull: Yes(0) No(1)
- ans is 2... w=1/2
- 11 years agoHelpfull: Yes(0) No(1)
- w=1/2 and the ans is 2.

- c
we get 2w=1 - 11 years agoHelpfull: Yes(0) No(0)
- 13=13w/(1-w) if we write in the equation form we get 13-26w=0 if we solve this we get w=1/2 then w value in the 2(2w)=1*1/2*2=2
so ans is 2 - 10 years agoHelpfull: Yes(0) No(0)
- 2w=1, (2w)2 is (2w)^2 right? then the answer is (2*1/2)^2=1.

- w=1/2
s0 13*(1/2)/(1-1/2)=(13/2)*(2)=13
:::w=1/2
2w*2=2(1/2)*2===2 - 10 years agoHelpfull: Yes(0) No(0)
