CAT 2018 Alligations and Mixtures — Previous Year Question

A mixture comprises water and liquids A and B. The volume of water is $1/3$rd of the total mixture and the volume of liquids A and B are in the ratio $5:3$. To remove the water, the mixture is passed through a porous medium which completely absorbs the water and partially absorbs liquid A. Altogether this porous medium absorbs $200$ ml of the initial mixture. If the ratio of volume of liquids A and B in the residual concentrated mixture becomes $7:9$ then nd the volume of water absorbed by the porous medium.
