) If the numerator of a fraction is increased by 25% and denominator decreased by 20%, the new value is 5/4. What is the original value?

a) 3/5

b) 4/5

c) 7/8

d) 3/7

• let numerator is x nd denominator is y.if we increase x by 25% den it will be 125x/100 nd if u decrease y by 20% thn value will be 80y/100. then new value is 125x/80y=5/4 .or x/y=4/5. hence d answr is - b)4/5

• let x/y be the original value
  then acc to qustn : (x+.25x)/(y-.2y) = 5/4
  ==>(1.25x/0.8y)=5/4
  ==>x/y= 4/5

• answer is 4/5
• 12 years agoHelpfull: Yes(3) No(1)
• b
  (1.25X)/0.8Y = 5/4
  --> X/Y = 4/5

• LET US GO BY VERIFYING OPTIONS
  25% OF 4 IS 1
  20% OF 5 IS 1
  SO ANSWER IS 4/5

• (x*125)/(80*y)=5/4 solve and ans=4/5

• ans :4/5
  consider numerator and demoninator are x,y then
  x+(x*25/100) 5
  ------------------ = -------
  y-(y-20/100) 4
  if we solve it we will get 4/5 x=5 and y=4

• b) 4/5
  x= numerator. x= 5/1,25 (as increase was 25%) y=denominator, y=4/0.80(as decrease was 20%)
  on equating x/y=4/5

• (x*125)/(y*80)=5/4.... on solving x/y=4/5
