What direct labour cost should have been incurred to prepare 6.000 meals? How much does this differ from the actual direct labour cost? 2. Break down the difference computed in (1) above into a labour rate variance and a labour efficiency variance Problem 2 Material and Labour Variances The direct materials and direct labour standards for one bottle of Whisper perfume, a product of the Farante Company, are given below. Standard Quantity Standard Price Standard or Hours or Rate Cost Direct materials Direct labour 72 grams 0.4 hours $2.50 per gram $10.00 per hour $18.00 $400 During the most recent month, the following activity was recorded: a Twenty thousand grams of material were purchased at a cost of 2 40 per gram b. All of the material was used to produce 2,500 bottles of Whisper. c. Nine hundred hours of direct labour time were recorded at a total labour cost of $10 800 Required: 1. Compute the direct materials price and quantity variances for the month 2. Compute the direct labour rate and efficiency variances for the month. Problem 3 Comprehensive Variance Analysis Helix Company produces several products in its factory, including a karate robe. The company uses a standard cost system to assist in the control of costs. According to the standards that have been set for the robes, the factory has a denominator activity level of 780 direct labour hours each month, which should result in the production of 1,950 robes. The standard costs associated with this level of production are as follows: Total Per Unit of Product Direct materials Direct labour Variable manufacturing overhead Fixed manufacturing overhead $35,490 $ 7,020 $ 2.340 $ 4,680 $18.20 3.60 1.20 2.40 $25.40 "Based on direct labour-hours During April, the factory worked only 760 direct labour-hours and produced 2,000 robes.

All of the materials purchased during the month were used in production. Required: Compute the following variances for April: 1. The materials price and quantity variances 2. The labour rate and efficiency variances. 3. The variable manufacturing overhead spending and efficiency variances. 4. The fixed manufacturing overhead budget and volume variances
