Well, it's been awhile since I've done this but my answer would be 24 liters must evaporate to make a 5% solution.
60 * .03 = 1.8 ~ That's what you have. The 1.8 is how many liters of salt you have.
60 = x ~ Replace 60 with x.
x * .05 = 1.8 ~ The percentage of salt is now 5 but you still have 1.8 liters.
1.8/.05=36 ~ algebra...
60 - 36 = 24 ~ Total minus how much will remain gives you the total that must evaporate. I know you could have followed them easily enough without the notes. They were more for me so I knew I'd done it correctly. :-) Hope it's right and .

A chemist is making 200 L of a solution that is 62 percent acid He is mixing an 80 percent acid solution with a 30 percent acid solution How much of the 80 percent acid solution will he use?
The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
