If 13 = 13w/(1-w) ,then (2w)2 =

A.1/4
B.1/2
C.1
D.2

• given
  13 = 13w/(1-w)
  or 1=w/1-w
  or 1-w=w
  or 2w=1
  so (2w)2=1*2=2

• 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

• 13=13/1-w
  
  13-13w=13w
  23w=13
  W=1/2
  (2w)2=2

• ans is 2... w=1/2
• 10 years agoHelpfull: Yes(0) No(1)
• w=1/2 and the ans is 2.

• c
  we get 2w=1
• 10 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

• 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
