  • Question
  • A jar was full with honey. A person used to draw out 20% of the honey from the jar and replaced it with sugar solution. He has repeated the same process 4 times and thus there was only 512 gm of honey left in the jar, the rest part of the jar was filled with the sugar solution. The initial amount of honey in the jar was:


  • Options
  • A. 1.25 kg
  • B. 1 kg
  • C. 1.5 kg
  • D. None of these

  • Correct Answer
  • 1.25 kg 

    Explanation

    Let the initial amount of honey in the jar was k, then

     

      512   =   k 1   -   1 5 4   o r     512   =   k 4 5 4  

     =>  k   =   512   ×   625 256  

    => k = 1250

     

     Hence initially the honey in the jar = 1.25 kg
