II. The standard cost of a chemical mixture is as follows: 60% of Material A @ USD 50 per kg 40% of Material B @ USD 60 per kg per kg A stand loss of 25% on output is expected in production. The cost records for a period has shown the following usage. 540 kg of Material A @ USD 60 260 kg of Material B @ USD 50 per kg The quantity processed was 680 kgs of good product. From the above given information, calculate: (i) Material Cost Variance Material Price Variance (iii) Material Efficiency Variance (iv) Material Mix Variance (v) Material Yield Variance
