Assume that Hypothetical Ltd uses direct labour-hours as the basis to allocate overheads to production. The variable overhead is budgeted at $ 160 per direct labour-hour in Department 1. The fixed manufacturing overhead is budgeted at a total of $ 16,00,000 per year and normal production volume has been established at 40,000 direct labour-hour per year. In Department 2, variable manufacturing overhead is budgeted at $ 100 per direct labour-hour and fixed overhead at $12,00,000 per year. Normal production volume is 80,000 labour-hours per year. Compute the standard overhead rates.
