4x, x

Total\: 5x

(9x-10)

4x-8/x-2+10 = 2/3

12x-24= 2x-16

10x=8

Or\: let \: A = 16 L

Then \: B = 4L

Total = 20 L

Now\: 10 L\: taken \: out = \frac{1}{2}\times 16

10 \: L \: remaining\: milk = 8 \: L \: taken

Water = 45/2 = 2L taken

Final = 8\: L\: milk

                 = 2L water

Now\: 10\: L \: added

8L, 12 L

So\: 8/12 = 2:3

A= 16
