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.

Another question is, in part B i and ii have increased and decreased 20% only in sales volume then why did they make changes in variable costs when as in iii and iv they have only evaluated in variable costs not change sales volumne
In ( III) and ( IV) there are change in variable cost because if sales volume are change then variable cost also change because variable cost varies with change in sales volume
variable cost meansa cost that varies with the level of output.
