I went for substition.

60

24 36 (2:3)


Chk ans: 10


4 6 (2:3)


Since 10 is removed ==> Remaining is (24-4 = 20 Milk and 36-6=30 Water)

Add 10 lit of pure milk = 30 Milk and 30 water = 60

Ans : 10

(2) is the answer

Container = 60 litres
Milk left after x litres were taken = 2/5*(60-x)
x litres of milk were added later
the proportion of milk to water in the resulting mixture was 1/2 to 1/2
therefore, 30 litres of milk were in the resulting mixture

=> 2/5*(60-x) +x = 30
=> x=10.

Easier still:

quantity of milk (finally) = 30 lit.
quantity of water (finally) = 30 lit.

Initial qualtity of milk = 24
Initial qualtity of water = 36

meaning 6 lit. of warer has been removed => 4 lit of milk has been removed. Therefore a total of 10 lit.of the solution has been removed!! :banana
