The standard raw materials cost of producing 300 units of Product A were as follows: 600 units of Raw Materials @ 50 per unit 330,000 But actual Raw Materials cost of producing 300 units of Product A were 1000 units of Raw Materials @ * 40 per unit 40,000. Determine (i) Raw Materials Cost Variance, (ii) Raw Materials Price Variance, (iii) Raw Materials Usage Variance
