Seems like some of the answers in XAT mock test 1 are wrong . Even i didnot get the meaning 1 metres/min for rate of flow ?

If you have any doubts in the mock tests. You can ask experts doubts for every question.At the end of each question, you will find a dialog box for asking doubts. They will explain your doubts in the comment section.

Even in the DM section answers and especially solutions doesnot seem to be satisfactory.
