Using the information in P26.1, compute the overhead controllable variance and the overhead volume variance.

Data from P26.1:

Tjandra Company manufactures a single product. The standard cost per unit of product
is shown below.

Direct materials—1 kilogram plastic at €7.00 per kilogram......................................€ 7.00

Direct labor—1.6 hours at €12.00 per hour................................................................19.20

Variable manufacturing overhead................................................................................12.00

Fixed manufacturing overhead......................................................................................4.00

Total standard cost per unit.........................................................................................€42.20

The predetermined manufacturing overhead rate is €10 per direct labor hour (€16.00 ÷ 1.6). It was computed from a master manufacturing overhead budget based on normal production of 8,000 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of €60,000 (€7.50 per hour) and total fixed overhead costs of €20,000 (€2.50 per hour). Actual costs for October in producing 4,800 units were as follows. 

Direct materials (5,100 kilograms).............................................................€ 36,720

Direct labor (7,400 hours)...........................................................................92,500

Variable overhead.......................................................................................59,700

Fixed overhead.............................................................................................21,000

Total manufacturing costs........................................................................€209,920

The purchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored.
