Potatoes are made up of 99% water and 1% potato matter. Jack bought 100 pounds of potatoes and left them outside in the sun for a while. When he returned, he discovered that the potatoes had dehydrated and were now only made up of 98% water. How much did the potatoes now weigh?

• 100 POUNDS = 99 WATER + 1 POTATO MATTER
  LETS SAY NOW ITS X POUNDS
  0.98X+1=X
  X=50 POUNDS .......ANS

• initially water weigh 99 pounds & patato matter weigh 1 pound.
  
  after dehydration
  water = 98%
  => potato matter = 2% = 1 pound
  100% = (1/2) * 100 = 50 pounds
  
  So, potato now weigh 50 pounds.

• Initial weight of water = 99% of 100 pounds = 99 pounds
  so, initial weight of potato matter = 1 pound.
  After Dehydration:-
  98% water. i.e 2% potato matter.
  2% = 1 pound
  So, 100% = (1/2)*100 = 50 pounds

• If 100 pounds of potatoes is 1% potato matter, then that means there is one pound of potato matter. After the potatoes dehydrated somewhat, this one pound accounted for 2% of the total mass (with the remaining 98% being water). One pound is 2% of 50 pounds, so the total mass of the potatoes after sitting out in the sun is 50 pounds.

• now the total weigt of potatos will be it's first weight's (98+1)or 99%
  that means= 100*99%=99 pounds
• 13 years agoHelpfull: Yes(3) No(13)
• 100 POUNDS = 99 WATER + 1 POTATO MATTER
  LETS SAY NOW ITS X POUNDS
  0.98X+1=X
  X=50 POUND

• Initially, weight of water 99% and of potato-content is 1%
  Out of a total weight of 100 pounds, weight of water is 99 pounds and weight of potato-content is 1 pound.
  After dehydration, let the total weight be ‘x’.
  
  Total weight
  Weight of water
  Weight of “potato content”
  Initially
  100
  99
  1
  After Dehydration
  x
  0.98 * x
  0.02 * x
  “After dehydration, weight of potato content does not change”
  0.02 * x = 1
  x = 1/0.02 = 100/2 = 50
