Answer 2

Explanation:

Let the capacity of each = 100 ml

So 300 ml removed and poured into second

First vessel = 200 ml water

Second = 500 ml water+ 300 ml A

Ratio = 5:3

Proportion of water = 3/8

If 300 ml removed from second  = 300 x 5/8 = 187.5 ml water

= 112.5 ml water

Now poured so vessel = 200 + 112.5 = 312.5 A

= 187.5 ml

Hence ratio = 5:3 proportion of water = 3/8

So A= B
