Using the process data (10,000 units started, 8,000 completed, 2,000 in progress that are 100% complete for materials and 50% for conversion; materials cost £60,000 and conversion costs £44,000), what is the value of the closing work in progress, to the nearest pound?

Answer and explanation

Correct answer: B. £16,889

  1. Step 1: Materials: 10,000 equivalent units, so £60,000 ÷ 10,000 = £6.00 per unit.
  2. Step 2: Conversion: 9,000 equivalent units, so £44,000 ÷ 9,000 = £4.8889 per unit.
  3. Step 3: Closing WIP = 2,000 × £6.00 + 1,000 × £4.8889 = £12,000 + £4,889 = £16,889.
Answer
£16,889.
Why not the others: £21,778: This values the work in progress as if it were fully complete for conversion costs. £12,000: This values only the materials in the closing work in progress and leaves out conversion costs. £20,800: This spreads total cost over the 10,000 units started without using equivalent units.
