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 ?

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

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.
