Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

This diagram is a mix of two curves. Demand curve where there is a negative relation between price (AR) and qauntity demanded and second it is showing the relation between TR AND MR, the rectangular box is depicting the TR and it is maximum at its right side upper point( at a particular price and quantity) straight below on x axis you can see the MR CURVE which is 0 at THE SAME quantity. So can confirm that TR is max when mr= 0.... now above this point mr is positive and one can conclude when mr positive price elasticity of demand > 1 and vice versa.
