5 liter jug question?:)?

Question

A 5 litre jug contains 4 litres of a salt water solution that is 15 percent salt. If 1.5 litres of the solution
spills out of the jug, and the jug is then filled to capacity with water,approximately what percent of the
resulting solution in the jug is salt?
(A)7.5% (B)9.5% (C) 10.5% (D)12% (E)15%

Answer 1

When 1.5 L spills from the original 4 L solution, that leaves 3.5 L. The amount of salt would be (15%)*(3.5 L) = 0.525 L. The final volume of the solution is the full 5 L capacity of the jug, so the salt content will be (0.525 L) / (5 L) = 0.105 = 10.5%, answer C.

Answer 2

(a)7.5%
