From the following data, compute the fi xed-overhead variances:

Budget output for the year: 30,000 units.

Budget fi xed overheads for the year: Rs. 30,000.

Standard production per hour: 15 units.

Actual output for the month: 2,550 units.

Actual overheads for the month: Rs. 3,000.

The year is budgeted to 50 working weeks on a 40-hour week basis. Two hours in every week are lost due to abnormal idle time. The month consists of four working weeks.

The unit has to curtail its production operation to 4 days in a week instead of the usual 5 days as a result of power cut.
