by weight , liquid x makes up 1.5 percent of solution p and 6.5 percent of solution q . if 400 grams of solution p are mixed with 600 grams of solution q , then liquid x accounts for what percent of the weight of the resulting solution ?
"the number of grams of liquid x is 1.5 ( 400 ) / 100 + 6.5 ( 600 ) / 100 = 6 + 39 = 45 grams . 45 / 1000 = 4.5 % the answer is d ."
multiply(divide(add(const_1, divide(multiply(6.5, 600), const_100)), const_1000), const_100)
