Rexi Manufacturers makes a single product, X, using a single raw material A. Standard costs relating to X have been calculated as follows. Standard cost schedule Per Unit (Rs) Direct material, A, 10kg at Rs. 20 per kg 200 Direct labour, 5 hours at Rs.6 per hour 30 Variable production overhead, 5 hours at Rs.1 per hour 5 Fixed production overhead, 5 hours at Rs.10 per hour 50 Standard cost 285 Standard profit 95 Standard selling price 380 The company expects to produce 900 units in month of April 2019. During April 2019 the actual results are as follows. 800 units of product X were produced and sold at Rs. 312,000. 7800 kgs costing Rs. 159,900 were bought and used. 4200 hours were worked during the month and total wages were Rs. 24,150. The variable production overhead for the month was Rs. 4,900. The fixed production overhead for the month was Rs. 47,000
