solution y is 30 percent liquid x and 70 percent water . if 3 kilograms of water evaporate from 8 kilograms of solution y and 3 kilograms of solution y are added to the remaining 6 kilograms of liquid , what percent of this new solution is liquid x ?
in 8 kilograms of solution y there are 0.3 * 8 = 2.4 kilograms of solution x ; after 3 kilograms of water are replaced by 3 kilograms of solution y , to the existing 2.4 kilograms of solution x , 0.3 * 3 = 0.9 kilograms of solution x are added , so in the new solution of 8 kilograms there are 2.4 + 0.9 = 3.3 kilograms of solution x , which is 3.3 / 8 * 100 = 41.3 % of this new solution . answer : c .
multiply(const_100, divide(add(multiply(8, divide(30, const_100)), multiply(3, divide(30, const_100))), add(add(multiply(8, divide(30, const_100)), multiply(3, divide(30, const_100))), add(subtract(multiply(8, divide(70, const_100)), 3), multiply(3, divide(70, const_100))))))
