Saraswathy  (10 years ago)

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

savita kumari  (9 years ago)

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

Dheeraj  (9 years ago)

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)

varsha shiveshwar  (9 years ago)

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.

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.

Rhythm Arora  (9 years ago)

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

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

Is this solution Helpfull? Yes | No (1)  

Ramya Dasari  (8 years ago)

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
