solution p is 20 percent lemonade and 80 percent carbonated water by volume ; solution q is 45 percent lemonade and 55 percent carbonated water by volume . if a mixture of pq contains 65 percent carbonated water , what percent of the volume of the mixture is p ?
"65 % is 15 % - points below 80 % and 10 % - points above 55 % . so the ratio of solution p to solution q is 2 : 3 . mixture p is 2 / 5 = 40 % of the volume of mixture pq . the answer is b ."
multiply(divide(subtract(divide(65, const_100), divide(55, const_100)), add(subtract(divide(65, const_100), divide(55, const_100)), subtract(divide(80, const_100), divide(65, const_100)))), const_100)
