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?

Answer / kart
total weight = 100 pounds; potato wt= 1pound;water 99 pound
now it has dehydrated and water is 98% of it and potato
matter is the remaining 2%
since weight of potato matter has not decreased
2%=1pound
therefore total weight now 100%=50 pounds

Answer / kerren (ko)
Okay so Kart had the right answer, I just want to explain it a little differently :)!!
Let's define: m = m_{water} + m_{potato}
Then m = 0.01*V*rho_{water} + 0.99*V*rho_{potato}
Where V is the volume of the potatoes and the rhos are the densities of the potato content and water.
The mass of the potato does not change (only the mass of the water) so m_{potato} remains constant!
The next day the new mass can be defined as:
m' = m_{water}' + m_{potato}'
BUT remember m_{potato} remains constant so m_{potato}' = m_{potato}
m' = 0.98*V'*rho_{water} + 0.02*V'*rho_{potato}
So we now know that the mass of the potato before is equal to the mass of the potato after, therefore:
0.01*V*rho_{potato} = 0.02*V'*rho_{potato}
Which leads to:
V'/V = (0.01*rho_{potato})/(0.02*rho_{potato})
So
V'/V = 0.5
And the ratio of mass will be the same as the ratios of volume:
V'/V = m'/m = 0.5
Therefore:
m'/100lb = 0.5
m' = 50lb

Answer / manikandan
100 pounds of potatoes contain 99lb of water and 1lb of
potato matter before dehydration. so after dehydration, it
evoporated only the water 1 lb . so the current weight
would be 99 lb.i.e 98water + 1 potato

Answer / ankur bansal
100 pounds make 400*100=40,000 gms means 40 kgs
98% of water+ 1% of potato material makes it 99%
weight of potatoes is now= 99*(40/100)=39.6 kg
