Jurong Bhd operates the standard costing system. The standard/budgeted material costs for producing 400 litres of cooking oil are as follows:

Materials	Quantity (litre)	Unit Cost (RM)	Amount (RM)
A	100	2	200
B	250	1	250
C	150	3	450
Total	500		900

In January, the company produces 4,000 litres of cooking oil and the actual usage and the cost of the materials are as follows:

Materials	Actual Usage (litre)	Actual Purchase (litre)	Unit Cost (RM)
A	1,500	2,000	2.2
B	3,000	4,000	1
C	1,500	2,000	2.8
Total	6,000	8,000

In addition, Jurong Bhd had budgeted to sell 180,000 of its product at a price of RM8; this would give a standard contribution of RM2 per unit. The sales budget had been based on holding its market share in a total market of 3.6 million high quality cooking oil.

After the end of the year, Jurong Bhd found that it had sold 176,000 units of cooking oil at an average price of RM7.50, but that the total market had been 3.5 million.
