1 units of product A requires 7 kg of material X and 3 kg of material Y. The standard price of X is OMR 2.5 and that of Y is OMR 3. During the month 600 units of A is produced. The actual quantity used is 4,000 kg of X and 2,200 kg of Y at the actual price of OMR 3 for X and OMR 2 for Y. Calculate material Cost variance. O a. 1,500 adverse O b. 500 Adverse O c. 1,500 favourable d. 500 favourable 4,000 units are introduced in a process. Normal loss is 5%. During the process 3,400 units are completed and transferred to next process. 200 units are lost due to an accident (100% complete) and 400 units are not completed yet. If the degree of completion of incomplete units is material 80% and Labour 50%, completed units for material and labour will be: O a. Material 3,680 units and labour 3,800 units O b. Material 3,800 units and labour 3,900 units O c. Material 3,920 units and labour 3,800 units d. Material 3,800 units and labour 3,725 units
