In a fraction, if 1 is added to both the numerator and denominator, the fraction becomes 1/2. If
numerator is subtracted from the denominator, the fraction becomes 3/4. Find the fraction.
1] 5/8 2] 3/7 3] 2/3 4] 1/8

• Let d original fraction be x/y
  (x+1)/(y+1) = 1/2
  2x+2 = y+1
  y = 2x+1
  
  x/(y-x) = 3/4
  x/(2x+1-x) = 3/4
  x/(x+1) = 3/4
  4x = 3x+3
  x = 3
  y = 2(3)+1 => y=7
  Fraction is x/y => 3/7
  
  Ans : (2) 3/7

• 3/7
  by applying the condition on options the suitable fraction is 3/7.
  (3+1)/(7+1)= 4/8=1/2
  and 7-3=4 therefre the frction becomes 3/4 on subtractin numerator frm denominator .

• If
  numerator is subtracted from the denominator, the fraction becomes 3/4....how can we analyse this statement???

• "Numerator is subtracted from the denominator" =>
  denom. is y... from y, subtract x... so y-x
  Assuming numerator remains same... so x/(y-x)

• Ans:2.3/7
  2x+2=y+1
  x/(y-x)=3/4
  Solve them.

• the eq will be
  (x+1)/(y+1)=1/2
  &
  x/(y-x)=3/4
  
  After solving and equating both we get x=3 & y=7
  so the fraction will be 3/7

• its 3/7
  coz 3+1/7+1=1/2 and 3/7-3=3/4

• 3/7 is the ans
• 9 years agoHelpfull: Yes(0) No(0)
• Let the fraction be x/y.Then x/(y-x)=3/4
  i.e. x/y=3/7
