✓ VerifiedAnswer: (A) ₹20,70,000; ₹23,40,000
Since the proposal is on cash cost basis, depreciation is excluded from all computations.
Total Manufacturing Cost (Cash Basis):
- Raw Material Consumed = 25% of Sales = 25% × ₹30,00,000 = ₹7,50,000
- Wages = 20% of Sales = 20% × ₹30,00,000 = ₹6,00,000
- Cash Manufacturing Overhead: The outstanding balance at year-end is ₹60,000, paid in one month arrear. This means the monthly cash manufacturing overhead = ₹60,000, so annual = ₹60,000 × 12 = ₹7,20,000
Total Manufacturing Cost (Cash) = ₹7,50,000 + ₹6,00,000 + ₹7,20,000 = ₹20,70,000
Total Cost of Sales (Cash Basis):
To arrive at cost of sales, selling and administrative expenses are added to manufacturing cost:
- Administrative Cost = ₹1,80,000 (given)
- Sales Promotion Expenses = ₹90,000 (given)
Total Cost of Sales (Cash) = ₹20,70,000 + ₹1,80,000 + ₹90,000 = ₹23,40,000
Note: Depreciation, though part of cost of production as stated, is a non-cash item and is therefore excluded entirely from cash cost basis computations.
Write it like this
1The skeleton
- State the cash basis exclusion first — write 'Since the proposal is on cash cost basis, depreciation is excluded' as your opening line; examiner needs to see you know WHY numbers differ from normal costing.
- Build manufacturing cost in three clean lines — Raw Material → Wages → Cash Mfg Overhead, each with its own working; this layered presentation makes partial marking easy for the examiner.
- Crack the overhead trap with one sentence — explicitly state 'outstanding ₹60,000 = 1 month arrear, so monthly overhead = ₹60,000, annual = ×12'; if you just write ₹7,20,000 without this bridge, you lose the logic mark.
- Transition with a label before cost of sales — write 'Total Cost of Sales = Manufacturing Cost + Admin + Sales Promotion' so the examiner sees structure, not just numbers floating on a page.
- Box your two final answers together — write both ₹20,70,000 and ₹23,40,000 clearly labeled side by side or back-to-back; this is a 2-mark MCQ-style question and the examiner scans for these two figures instantly.

3Common trap
Heads up — the killer mistake here is treating ₹60,000 as the ANNUAL overhead instead of the monthly figure. The question says it's 'outstanding at year-end, paid in one month arrear' — that means ₹60,000 is one month's worth, so you must multiply by 12. Miss that bridge and your manufacturing cost is off by ₹6,60,000.
