A 5 litre jug contains 4 litres of a salt water solution that is 15 percent salt.
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?
Answer/Solution
7.5%
Steps/Work
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,then 2.5 ltrs of solution with 15% salt is left in jug.
If solution is now increased to 5 ltrs, the volume is doubled, then salt percentage is halved to 7.5%.
ANSWER:A
If solution is now increased to 5 ltrs, the volume is doubled, then salt percentage is halved to 7.5%.
