Let’s solve the questions in detail one by one based on the given information.
Q1: Accounting Concepts
1. Accrual Concept
  Recognize revenue and expenses when they occur, irrespective of cash flows.
  Example: A company recognizes revenue when the product is sold, even if the payment is due
  later.
2. Matching Concept
  Expenses should be recognized in the same period as the revenue they help generate.
  Example: If a company sells a product in December, the costs incurred in manufacturing it (even
  from earlier months) must be reported in December.
3. Prudence Concept
  Anticipate losses but not gains. Avoid overstating assets or income.
  Example: If inventory may lose value, record a provision for this loss immediately.
Q2: Cost Accounting
Definition:
Cost accounting tracks and analyzes the costs associated with production or operations to
optimize efficiency and profitability.
Elements of Cost:
1. Material Costs: Costs of raw materials consumed during production.
2. Labor Costs: Wages paid to workers directly involved in production.
3. Overheads:
     Factory Overheads (e.g., rent, utilities, maintenance).
     Administrative Overheads (e.g., salaries of office staff).
     Selling & Distribution Overheads (e.g., marketing, delivery costs).
Q3: Cost of Production
Data Provided:
          Particulars                  Amount (₹)
Raw Material Consumed        40,800
Direct Labour                Not mentioned (assume ₹10,000)
Factory Labour               ₹5,000
Factory Supervision Charges ₹2,000
Factory Rent & Lighting      ₹4,400
Oil for Machinery            ₹1,200
Depreciation (Factory)       ₹1,100
Office Overheads (Salary)    ₹15,000
Miscellaneous Office Expenses₹7,000
           Particulars                   Amount (₹)
Selling & Distribution Expenses ₹2,000
Step 1: Calculate Total Factory Cost:
                    Factory Cost = Raw Material + Direct Labour + Factory Expenses
                 = 40, 800 + 10, 000 + (5, 000 + 2, 000 + 4, 400 + 1, 200 + 1, 100) = ₹64, 500
Step 2: Add Office Overheads:
                       Total Cost of Production = Factory Cost + Office Overheads
                                 = 64, 500 + (15, 000 + 7, 000) = ₹86, 500
Step 3: Add Selling Expenses:
\text{Cost of Goods Sold} = \text{Total Cost of Production} + \text{Selling & Distribution}
                                    = 86, 500 + 2, 000 = ₹88, 500
Step 4: Add Profit:
Profit = 20% of Cost of Goods Sold
                          Selling Price = ₹88, 500 + (88, 500 × 0.20) = ₹1, 06, 200
Cost Per Unit:
                                    Cost Per Unit = Cost of Goods Sold
                                                      Number of Units
                                          88, 500
                                        =          = ₹88.50 per unit
                                           1, 000
Q4: FIFO (Closing Inventory)
Data Provided:
   Date   Units PurchasedPrice per Unit (₹)
05/04/2021300            12
08/04/2021350            13
09/04/2021150            15
10/04/2021250            17
Assume 600 units were sold. Under FIFO:
1. 300 units @ ₹12 → ₹3,600
2. 300 units @ ₹13 → ₹3,900
Remaining Inventory:
  50 units @ ₹13 = ₹650
  150 units @ ₹15 = ₹2,250
  250 units @ ₹17 = ₹4,250
                       Closing Inventory Value = ₹650 + ₹2, 250 + ₹4, 250 = ₹7, 150

Q6: Classification of Activities
1. Issue of Bonds: Financing activity (raising funds).
2. Purchase of Assets: Investing activity (outflow for long-term assets).
3. Purchase of Shares: Investing activity (outflow for investment).
4. Payment of Dividend: Financing activity (return to shareholders).

Q7: Asset Account
Data:
  Opening Balance: ₹10,00,000.
  Sold Machinery: ₹2,00,000 (purchased 1 July 2020, WDV depreciation 10%).
  Purchased Machinery: ₹3,50,000 (on 1 July 2021).
Calculation:
1. Depreciation on Sold Machinery (2020-2022):
                        Depreciation (Year 1) = 10% × ₹2, 00, 000 = ₹20, 000
                        Depreciation (Year 2) = 10% × ₹1, 80, 000 = ₹18, 000
Net Sale Value = ₹60,000.
2. Depreciation on New Machinery:
                            Depreciation = ₹3, 50, 000 × 10% × 9 = ₹26, 250
                                                              12
3. Depreciation on Remaining Assets:
                                     ₹8, 00, 000 × 10% = ₹80, 000
