Question 334078
In words:
(kg of salt in final solution)/(total kg of final solution) = 5%
Let {{{x}}} = kg of water that needs to be evaporated
given:
Salt in original solution: {{{.04*100 = 4}}} kg
------------------------------------
The final solution has {{{100 - x}}} kg of salt plus water
The original kg of salt never changes, so It
stays at {{{4}}} kg
