Final answer:
The total variable overhead cost variance is rs. 5000 adverse (3).
Step-by-step explanation:
The total variable overhead cost variance can be calculated by comparing the actual variable overhead cost with the budgeted variable overhead cost. In this case, the actual variable overhead cost is rs. 15000 and the budgeted variable overhead cost is rs. 10000. The total variable overhead cost variance is = Actual variable overhead cost - Budgeted variable overhead cost = rs. 15000 - rs. 10000 = rs. 5000. Therefore, the correct answer is option 3) rs. 5000 adverse.
