8 liters of a 25 percent solution of alcohol in water are mixed with 2 liters of a 12 percent alcohol in water solution . what is the percentage of alcohol in the new solution ?
the total amount of alcohol is 0.25 ( 8 ) + 0.12 ( 2 ) = 2.24 liters . the percentage is 2.24 / 10 = 22.4 / 100 which is 22.4 % the answer is d .
multiply(divide(add(multiply(8, divide(25, const_100)), multiply(divide(12, const_100), multiply(8, divide(25, const_100)))), add(8, 2)), const_100)
