when asked what the time is,a person answered that the amount of time left is 1/5 of the time already completed.what is the time.

a) 8 pm
b) 8 am
c) 12 pm
d) 12 am

• 1 day = 24 hrs,
  let x be the amount of time completed.
  so,time left=(24-x).
  i.e.
  (1/5)x=(24-x)
  =>x=20.
  so! time left is 24-20=4 hrs.
  Ans:time is : x = 20 hrs =8pm.

• 8pm
  
  (1/5)x + x = 24hrs . from this we can calculate x (no. of hours completed out of 24 hrs.)

• A day has 24 hrs,
  let x be the amount of time left.
  Therefore amount of time left=24-x
  hence according to given condition,
  x=1/5(24-x)
  which gives x=4....therefore the current time is 12(night)-4=8pm
  Hence according to the givin condition,

• Solution is a) 8pm
  because:
  completed are "x" hours
  left 1/5 of "x" hours
  => x+1/5x=24=12pm
  => 5/5x+1/5x=24
  => 6/5x=24
  => x=5/6*24
  => x=220/6=20=8pm
