there is 60 lit of milk and water in which milk forms 84 % . howmuch water must be added to this solution to make it solution in which milk forms 68 %
"60 * 84 / 100 = 50.40 lit milk that is 9.60 lit water let x lit water will be added then ( 60 + x ) * 68 / 100 = 50.40 so x = 14.11 answer : a"
subtract(multiply(divide(const_100, 68), divide(multiply(60, 84), const_100)), 60)
