To produce a 75% solution, it is required to add a total of 3.85 ounces of pure salt to the initial solution.

How many ounces of salt are there in the initial solution?

  • 11 oz = 100
  • x       = 40

  • x = 11 x 40 / 100
  • x =  4.4 oz

How many ounces of salt need to be added?

  • 4.4 oz = 40
  • x         = 75

  • x = 75 x 4.4 / 40
  • x = 8.25

  • 8.25 - 4.4 = 3.85 ounces
