variances

Ttaraf12y ago
Y plc produces widgets. Each should take 0.5 hrs to make. The standard rate is $10 per hr. Idle time is expected to be 5% of hours paid. They actually produce 10800 units. They pay $50000 for 6000 hrs, of which 300 hrs are idle. What is the labour efficiency variance?

Are you setting me a question?! It is not me who is taking the exam :-) I assume that you want help, but you do not say so. They actually work 6000 - 300 = 5,700 hours. The standard hours for the actual production are 10,800 x 0.5 = 5400 hours. So....they took 300 hours more than they should have done. We cost this out at the work rate which is 10/0.95 = $10.53 per hour. So the efficiency variance is 300 x 10.53 = 3159 (adverse). (If the 'work rate' confuses you, then you should watch the free lecture on this)
