TWO [25] 2.1. A standard quantity of 2 kilograms of material BB at a standard price of R4 per kilogram is allowed for the production of one unit of product Triple B. The cost figures for the first quarter of the year showed that 4 400 kg of material BB was purchased at R4,20 per kg. 2 000 units of product Triple B were produced using 4 200 kg of material BB. You are required to calculate the following variances for material BB: 2.1.1 Purchase price variance (4) 2.1.2 Issue price variance (4) 2.1.3 Quantity variance (4) 2.1.4 Total material variance for the 4 200 kg of material issued. (4) 2.2. To produce one unit of product Triple B a standard quantity of 4 direct labour hours at a standard rate of R6 per hour is allowed. The wage records show that it took 2 100 hours at R5,90 per hour to produce 500 units of product Triple B. You are required to calculate the following labour variances: 2.2.1 Labour rate variance (4) 2.2.2 Labour efficiency variance (3) 2.2.3 Total labour variance (2)
