Q 18
Rice Processors Plc uses a standard costing system. Fixed production overhead is absorbed on the basis of direct labour hours. The following data relate to a particular period of operation
Standard price of material/kg GHS5.90
Actual material issued to production 4,110kg
Standard labour hours 1,680
Actual direct labour hours 1,760
Actual fixed overhead GHS5,620
The following variance were calculated at the end of the period
GHS
Direct material cost 702(A)
Direct material usage 531(F)
Direct labour efficiency 336(A)
Direct labour cost 16 (F)
Fixed overhead cost 92(F)
Required
i standard quantity of materials
ii actual price of materials per kg
iii standard direct labour rate
iv actual direct labour rate
i) | Direct Material Usage Variance | = | (Standard Usage - Actual Usage) x Standard Price | ||||
$ 531.00 | = | (SU - 4110) x $ 5.90 | |||||
$ 90.00 | = | SU - 4110 | |||||
SU | = | 4200 |
ii) | Direct Material Price Variance | = | (Standard Price - Actual Price) x Actual Usage | |||||
$ -1,233.00 | = | ($ 5.90 - AP) x 4110 | ||||||
$ -0.30 | = | $ 5.90 - AP | ||||||

Direct Material Cost Variance | = | Direct Material Price Variance + Direct Material Usage Variance | ||||||
$ -702.00 | = | Direct Material Price Variance + 531 | ||||||
$ -1,233.00 | = | Direct Material Price Variance |
iii) | Direct Labor Cost Variance | = | Direct Labor Rate Variance + Direct Labor Efficiency Variance | |||||
$ 16.00 | = | Direct Labor Rate Variance + (- 336) | ||||||
$ 352.00 | = | Direct Labor Rate Variance | ||||||
Direct Labor Efficiency Variance | = | (Standard Hours - Actual Hours) x Standard Rate | ||||||
$ -336.00 | = | (1680 - 1760) x Standard Rate | ||||||
$ -336.00 | = | -80 x Standard Rate | ||||||
$ 4.20 | = | Standard Rate |
iv) | Direct Labor Rate Variance | = | (Standard Rate - Actual Rate) x Actual Hours | ||||
$ 350.00 | = | ($ 4.20 - AR) x 1760 | |||||
