If 12 ounces of a strong vinegar solution are diluted with 50 ounces of water to form a three-percent vinegar solution, what was the concentration of the original solution?

• 15.5%
  
  Let 12 ounce of vinegar solution contains x% of vinegar, then after diluting with 50 ounces of water percentage of vinegar is 3 in a diluted mixture.
  => (12x/100)/[12+50] = 3/100
  => 4x=62 or x= 15.5
