Find (7x + 4y ) / (x-2y) if x/2y = 3/2 ?

(a) 6 (b) 8 (c) 7 (d) data insufficient

• Correct Answer is not there in the given options.
  
  if x/2y = 3/2 then 2x = 6y i.e. x=3y
  
  (7x + 4y ) / (x-2y) = (7(3y) + 4y ) / (3y-2y)
  =25y/y = 25

• 25 is the answer
  x=3y
  substituting in equation we get 25

• x/y=3;
  x=3y;
  7x+4y=25y;
  x-2y=y;
  (7x+4y)/(x-2y)=25

• 25
  as given x/2y=3/2
  =>x=3y
  substituting this in the given exp. we will get the answer.
