Answer 1

Answer:

Hey Mate...

Step-by-step explanation:

Quantity of existing solution = 600 Litres

Amount of Acid in existing solution = 600 X 12%

                                                           = 600 X 12/100

                                                           = 72 Litres

Let the quantity of 30% acid solution to be added to x

Amount of acid in the added solution = 30% of x

                                                               = 30/100  X  x

                                                                = 0.3x
