Q. A container has 60 liters of a solution that is 40% acid. If 15 liters of the solution is removed and replaced with water, what is the new percentage of acid?
A.
30%
B.
35%
C.
40%
D.
25%
Solution
Acid removed = 40% of 15L = 6L. Remaining acid = 24L, new total = 60L, new acid % = (24/60)*100 = 40%.
Q. A solution contains 25% salt. If 8 liters of the solution is removed and replaced with water, what is the new concentration of salt in the solution?
A.
20%
B.
25%
C.
30%
D.
15%
Solution
Salt removed = 25% of 8L = 2L. New solution = 32L, new salt % = (25L / 32L) * 100 = 20%.
