    Answer:

    Initial quantity of milk is 36 liters

    Step-by-step explanation:

    Let total mix is 5x

    Milk is 3x and water is 2x

    Removed is 20 liters and balance is 5x-20

    (5x-20)*3/5 : (5x-20)*2/5+20 :: 2:3

    (5x-20)9/5=(5x-20)*4/5 +200/5

    45x-180=20x -80+200

    25x=300

    x=300/25=12

    Initial quantity of milk is 36 liters , water is 24 liters . Total mix is 60 liters

    Verification:

    Once 20l removed then mix is 40lit . milk is 24lit and water is 16 lit

    When 20 lit water added then milk is 24 lit and water is 36 lit. So ratio is 2:3 . It matches .

    Initial quantity of milk is 36 liters
