The standard cost card for a product shows,

Material cost 2 kg @ GH2.50 each = GH5.00 per unit

Labour 2 hours @ GH10 each = GH20 per unit

The actual which has emerged from business operations are as follows.

Production 8,000 units, material consumed 16,500 kg @ GH2.40 each = GH39,600,

Wages paid 18,000 hours @ GH8 each = GH144, 000

Calculate;

a) Labour Cost Variance

b) Labour Rate Variance

c) Labour Efficiency Variance

d) Material Cost Variance

e) Material Price Variance

f) Material Quantity Variance
