A bag with 100 kgs potatoes have 99% water. It is kept in the open under the sunlight. After sometime, little amount of water got evaporated and reduced to 98%. What is the weight now ?

• 100 * 99/100 = 99kg
  
  so 99kg of water nd 1kg of potato
  
  Given after evaporation, it gets reduced to 98%
  So water only ll get evaporated
  Weight of potato remains same (ie) 1kg
  
  Let d new weight be "x"
  
  x * 98 /100 = x-1 [ here am calculating weight of water. so subtracted weight of potato from total weight (ie) x-1]
  
  x=50kg
  
  so new weight = 50 Kg

• let the reduced weight be x kg
  (100-99)% of 100 kg = (100-98)% of x kg
  1% of 100 = 2% of x
  x = (1*100)/2 = 50 kg

• In 100 kg potato 99kg-water,1kg potato
  Water reduced to 98% ie (99*98)/100=97.02
  Plus 1kg of potato=98.02kg (weight after evoparating)

• water kg(litre, both r same as density is 1)=99; potato= 1kg;
  after evaporation, 98% of water is left out,
  therefore, 98/100 * 99 = 97.02kg.

• WHAT IS THE RIGHT ANS ........???????
  50 SEEMS TO BE CORRECT ONE........ BUT I AM LITTLE CONFUSE BETWEEN 50 AND 98.02

• how can reduction of 1% make the weight half of its orignal..

• Let me give the working part of it.
  
  99% 100kgs of potatoes is 99kgs. Remaining 1kg potato.
  
  then 98% of 99% of water out of 100kgs of potatoes comes to 97.02kgs
  
  Now adding the Kg of potato we get the
  
  final result 98.02 kgs of potatoes.

• here,the weight of potato remains constant
  therefore, water=99% potato=1%
  water=98% potato=2%
  now weight of potato is same, just the water has evaporated
  so 1* 1/100 = x* 2/100
  so x =50kg

• 98.02.50 is wrong
• 9 years agoHelpfull: Yes(1) No(0)
• whch ans is correct,is it 50 or 97.02

• pulp=(1/100)*100=1
  let wt be x
  after sometime( 2/100)*x=1
  x=50

• kg %
  100 99
  ? 98
  
  100 | x = 99|98
  
  so x=98.98kg

• as water reduced from 99% to 98% net difference in the weight is only 1kg hence after avaporation of water the weight will be 99kgs
