REQUIRED

1. The departmental manager was rushing off to a meeting and asked you to do the following:

1. Calculate the Standard direct labour hours for the months of May to October (rounded off to 2 decimal places) (3 marks)

1. Calculate the Direct labour efficiency variance for the months of May to October. (3 marks)

1. Are the labour efficiency variances for the months of May to October favorable or unfavorable? Briefly explain. (2 marks)

1. Assuming the actual labour rate is $16.00, calculate the direct labour rate (price) variances for each of the 10 months and label it as "F" for favourable variance or "U" for unfavorable variance. (Round-off all variances to the nearest whole number) (5 marks)

1. Suppose management investigates all direct labour efficiency variances in excess of 20 per cent of standard cost. Which month's variances will be investigated? (round-off all figures to the nearest whole number)

[Hint: Calculate the standard direct labour cost for the 10 months first]. Show ALL necessary workings. (5 marks)

1. Suggest possible causes for the variances that need to be investigated in requirement 3. (2marks)
