How many Kilograms of Pure water is to be added to 100 Kilograms of a 30% saline solution to make it a 10% saline solution.
Choose the correct choice from the following choices.
A) 100  B) 200  C) 300  D) 400  E) 500
Let x be the weights, in Kilograms, of pure water to be added. Let y be the weight, in Kilograms, of the 10% solution. Hence   x + 100 = y   x = 200 Kilograms.   Answer 200
