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
