Hi Chamak Lal,

          I am here to share my answer on your question. First of all, you mentioned 14 in the answer I think it as wrongly typed and considered it as one fourth(1/4). According to that my answer is water in bottle P is 8/11. And the ratio of water in A to Water in B is 3:8. Please comment  me whether it is right or wrong and if wrong then tell me the answer.

I hope my answer will be right.

Thank you.
