If a=2/3b , b=2/3c, and c=2/3d what part of d is b/
(a) 8/27
(b) 4/9
(c) 2/3
(d) 75%
(e) 4/3

• i thnk question will be what part of d is b/a
  so first b=2/3c=2/3*1/c=2/3*3d/2=d
  so b=d
  now if a=2/3b=2/3*1/b=2/3*1/d(because b=d)
  now b/a=d/(2/3d)=3d^2/2.
  2/3(b/a)=d^2
  d=4/9(d)
  so ans(b) is right.

• b=2/3c = (2/3)*(1/c) = (2/3)*(3d/2) = d .
  
  So, clearly b = d .
  
  no option seems to be correct.

• ans is 4/9
  b=2/3c
  =>b=(2/3(2/3d))
  b=4/9d
• 11 years agoHelpfull: Yes(8) No(8)
• 4/9 is the correct ans
  c=2/3d, c= 2/3b
  hence, d=3/2c, c=3/2b
  d=3/2*3/2= 9/4b
  hence, b=4/9d (ans)

• b=2/3c =>c=3/2b
  given c=2/3d
  => 3/2b=2/3d
  9/4b=d
  =>9b=4d
  d:b=4/9

• As b,c & d terms are not properly bracketed,it seems as if they are in denominator
  Ans is 4/9, if b=(2/3)c and c=(2/3)d->b=4d/9
  Ans is 1, if b=2/(3c) and c=2/(3d)->b=2*3d/3*2=d

• a=2/3b means a=(2/3)*b and b=(2/3)*c and c=(2/3)*d
  all r confuse and answer is b=(4/9)*d
  sol: c=2/3*d
  d=3c/2
  & b=2/3*c
  c=3b/2
  now put this value in equation d
  so,
  d=3*((3/2)*b)/2
  d=(9/4)*b
  b=(4/9)*d ans

• the problem should be in the form of a=2b/3, b=2c/3 and c-2d/3 then we can get d=4b/9 if they have given this type of question it seems that its an dummy

• b=2/3c=(2/3)(2/3)d
  
  =>b=4/9d
• 11 years agoHelpfull: Yes(1) No(0)
• as given
  a/b=2/3,b/c=2/3,c/d=2/3
  so (a/b)*(b/c)*(c/d)=8/27
  a/d=8/27
  as we know
  a=2/3b
  so bd=8/27*3/2
  b/d=4/9

• b=4/9(d) is correct as per PARAG
• 11 years agoHelpfull: Yes(0) No(2)
• d=2/3c=2/3*2/3b=b
  so ans is 1 which is not in the given options!
  
• 11 years agoHelpfull: Yes(0) No(0)
• 4/9
  b=2/3*2/3d=4/9d
• 11 years agoHelpfull: Yes(0) No(0)
• if b=2/3b and c=2/3d then clearly we have tofind out part of d is b then
  we put value of constant term c in b to get d that 4/9 of d so ans is (b).

• b=2/3*2d/3
  
  d=4b/9

• here answer is 4/3 because 4d=3b
• 10 years agoHelpfull: Yes(0) No(0)
• b) 4/9 is the right answer
• 8 years agoHelpfull: Yes(0) No(0)
• c=(2/3)d
  =>d=(3/2)c
  =>d=(3/2)(3/2)b Since b=(2/3)c c=(3/2)b
  =>d=(9/4)b
  But the question is what part of d is b so definitely x(let) part of d is b, therefore
  =>b=(4/9)d
  And hence x will be (4/9). Answer
• 7 years agoHelpfull: Yes(0) No(0)
• answer is (b) 4/9
  b=2/3c and c=2/3d
  so, b=2/3*(2/3d)=4/9d
  
  
  -there is no problem of brackets as options are clearly given. if there is option of "none of these", then we consider the problem of brackets.
