A You are required to calculate the overhead variances in the following cases:

(a) Budgeted for \(£ 37,000\) fixed overhead. The actual fixed overhead turns out to be \(£ 36,420\).

(b) Budgeted for production of 500 units in 250 hours. The variable overhead rate is \(£ 6\) per hour. In fact 500 units are produced in 242 hours.

(c) Budgeted for \(£ 18,000\) variable overhead and 9,000 machine hours. Actual overhead is \(£ 18,000\) and actual machine hours 8,820 .

(d) Budgeted for \(£ 9,000\) variable overhead and 3,000 machine hours. Actual overhead is \(£ 8,790\) and actual machine hours 3,000 .

(e) Budgeted for \(£ 120,000\) fixed overhead. The actual fixed overhead turns out to be \(£ 129,470\).

(f) Budgeted for production of 10,000 units in 30,000 hours. Standard variable overhead rate is \(£ 8\) an hour. In fact 9,880 units are produced in 30,000 hours.
