Fixed overhead absorption rate
= Budgeted overhead ÷ Budgeted output
= 100,000 ÷ 50,000
= Rs 2 per unit
Absorbed fixed overhead for actual output
= 54,000 × 2
= Rs 108,000
Fixed overhead cost variance
= Absorbed overhead − Actual overhead
= 108,000 − 120,000
= Rs 12,000 Adverse
Why adverse:
Actual fixed overhead was more than the overhead absorbed into production, so it is an adverse variance.
So the correct answer is Rs 12,000 A.
