quantity of potato will reamin same after drying so
(100-98)% of 100= (100-50)% of x
by solving this we get
x= 4kg - 12 years agoHelpfull: Yes(13) No(0)
- there are only 2 kg of "solid" potato to start with (98 kg is water)
when water reduces to 50%,
"solid" potato: water = 50:50 = 1:1 = 2kg:2 kg
so wt. of potato now = 4 kg - 12 years agoHelpfull: Yes(11) No(0)
- 49+(100-98) = 51
