Accepted Answer

**Note:** The transaction data table (15-12-19 to 31-01-20) was not included in the question as presented. The solution below provides the complete methodology and formulae a CA student must apply. Once the table data is available, substitute actual figures into each step.

---

**(i) Re-order Level**

**Re-order Level = Maximum Rate of Consumption × Maximum Lead Time**

This is the stock level at which a fresh purchase order must be placed. It ensures stock does not fall to zero before new supplies arrive.

**(ii) Maximum Stock Level**

**Maximum Stock Level = Re-order Level + Re-order Quantity − (Minimum Rate of Consumption × Minimum Lead Time)**

This is the upper limit beyond which stock should not be held, to avoid over-investment and storage costs.

**(iii) Minimum Stock Level**

**Minimum Stock Level = Re-order Level − (Normal Rate of Consumption × Normal Lead Time)**

This is the safety/buffer stock below which stock should not normally fall. It guards against stockouts due to unexpected demand or supply delays.

**(iv) Store Ledger — January 2020 (Weighted Average Cost Method)**

Under the **Weighted Average Cost (WAC) method**, a new weighted average rate is computed after every receipt (purchase), and issues are priced at this running average rate.

**Format of Store Ledger:**

**Key rule:** After each receipt — New WAC Rate = (Value of exis…

Question 2

From the following information, CALCULATE employee turnover rate: No. of workers as on 01.01.2019 = 3,600; No. of workers as on 31.12.2019 = 3,790; During the year, 40 workers left while 120 workers were discharged. 350 workers were recruited during the year, of these 150 workers were recruited because of exits and the rest were recruited in accordance with expansion plans.

Accepted Answer

**Employee Turnover Rate Calculation**

The following information is derived from the given data:
- Workers on 01.01.2019 = 3,600; Workers on 31.12.2019 = 3,790
- **Average Number of Workers** = (3,600 + 3,790) / 2 = **3,695**
- Total Separations = Workers left + Workers discharged = 40 + 120 = **160**
- Total Recruitments = 350; Replacements (due to exits) = **150**; New Accessions (expansion) = 350 − 150 = **200**

**(i) Separation Method:**
This method measures turnover based on the number of employees who left (separated) during the period.
Employee Turnover Rate = (Number of Separations / Average Workers) × 100 = (160 / 3,695) × 100 = **4.33%**

**(ii) Replacement Method:**
This method considers only those recruits who were hired to replace separated employees (i.e., actual replacements, not new additions).
Employee Turnover Rate = (Number of Replacements / Average Workers) × 100 = (150 / 3,695) × 100 = **4.06%**

**(iii) New Recruitment Method (Net Labour Turnover / Accession Method):**
This method captures the additional (net new) workers recruited purely for business expansion, excluding replacements.
Employee Turnover Rate = (New Accessions for Expansion / Average Workers) × 100 = (200 / 3,695) × 100 = **5.41%**

**(iv) Flux Method:**
This is the most comprehensive method — it accounts for all movements (both separations and total joinings) during the period.
Employee Turnover Rate = (Number of Separations + Total Recruitments) / Average Workers × 100 = (160 + 350) /…

Question 3

ABC Ltd. has three production departments P1, P2 and P3 and two service departments S1 and S2. The following data are extracted from the records of the company for the month of January, 2020: [table with overhead costs and departmental details including rent, lighting, wages, power, depreciation, insurance, along with machine horse power, cost of machinery, floor space, light points, and production hours data]

Accepted Answer

**Note: The original data table was not included in the question (shown as a placeholder). The solution below uses assumed but internally consistent data representative of the standard ICAI CA Intermediate illustration for this topic. Students must substitute their actual table values and follow the same steps.**

**Step 1 – Primary Distribution of Overhead**

Overhead items are apportioned to all five departments using appropriate bases:
- **Rent & Rates** – Floor Space (sq. ft.)
- **Lighting** – Number of Light Points
- **Wages of Foreman** – Number of Workers
- **Power** – HP of Machines
- **Depreciation on Machinery** – Cost of Machinery
- **Insurance on Machinery** – Cost of Machinery

After primary distribution (using assumed data — see working notes), the department-wise overhead is:

| Dept | Primary Overhead (₹) |
|------|----------------------|
| P1 | 12,400 |
| P2 | 9,020 |
| P3 | 6,640 |
| S1 | 2,610 |
| S2 | 1,430 |
| **Total** | **32,100** |

**Step 2 – Secondary Distribution (Reapportionment of Service Departments)**

Service departments do not directly absorb overhead; their costs are reapportioned to production departments using the given usage ratios.

S1 is reapportioned to P1:P2:P3:S2 in ratio 45:15:30:10 (assumed).
S2 is then reapportioned to P1:P2:P3 in ratio 60:35:5 (assumed).

After secondary distribution:

| Dept | Total Overhead (₹) |
|------|--------------------|
| P1 | 14,589.10 |
| P2 | 10,003.35 |
| P3 | 7,507.55 |

From the following data of Arnav Metallic Ltd., CALCULATE Cost of production: Repair & maintenance paid for plant & machinery ₹9,80,500; Insurance premium paid for plant & machinery ₹96,000; Raw materials purchased ₹64,00,000; Opening stock of raw materials ₹2,88,000; Closing stock of raw materials ₹4,46,000; Wages paid ₹23,20,000; Value of opening Work-in-process ₹4,06,000; Value of closing Work-in-process ₹6,02,100; Quality control cost ₹86,000; Research & development cost ₹92,600; Administrative cost for Factory & production ₹9,00,000 and Others ₹11,60,000; Amount realised by selling scrap ₹9,200; Packing cost ₹10,200; Salary paid to Director (Technical) ₹8,90,000

Accepted Answer

**Cost Sheet of Arnav Metallic Ltd. — Cost of Production**

**Step 1 — Raw Material Consumed:**
Opening Stock of Raw Materials ₹2,88,000 plus Purchases ₹64,00,000 minus Closing Stock ₹4,46,000 = **₹62,42,000**

**Step 2 — Prime Cost:**
Raw Material Consumed ₹62,42,000 plus Wages Paid ₹23,20,000 = **₹85,62,000**

**Step 3 — Factory/Works Overhead:**
Repair & Maintenance (Plant & Machinery) ₹9,80,500; Insurance Premium (Plant & Machinery) ₹96,000; Administrative Cost — Factory & Production ₹9,00,000; Quality Control Cost ₹86,000; Research & Development Cost ₹92,600; Salary — Director (Technical) ₹8,90,000; Less: Scrap Realised (₹9,200) = **₹30,35,900**

**Step 4 — Works Cost:**
Prime Cost ₹85,62,000 + Factory Overhead ₹30,35,900 = **₹1,15,97,900**

**Step 5 — Adjust for Work-in-Process:**
Works Cost ₹1,15,97,900 + Opening WIP ₹4,06,000 − Closing WIP ₹6,02,100 = **₹1,14,01,800**

**Step 6 — Add Administration Overhead (Others):**
Administrative Cost — Others ₹11,60,000 (office/general administration overhead is added after works cost to arrive at Cost of Production per standard cost sheet structure).

**Cost of Production = ₹1,14,01,800 + ₹11,60,000 = ₹1,25,61,800**

**Notes on treatment of items:**
- **Scrap Realised** ₹9,200 is deducted from factory overhead as it reduces factory cost.
- **Director (Technical) Salary** is treated as factory overhead since the technical director directly oversees production.
- **R&D Cost** ₹92,600 is included in factory/works overhead as it rel…

Question 6

The following are the balances existed in the books of JPG Ltd. for the year ended, 31st March, 2019: Stores Ledger Control A/c ₹30,00,000; WIP Control A/c ₹15,00,000; Finished Goods Control A/c ₹25,00,000; Manufacturing Overheads Control A/c ₹1,50,000; Cost Ledger Control A/c ₹68,50,000. During the year 2019-20, the following transactions took place: [detailed list of transactions including finished product, manufacturing overhead, raw material purchased, factory wages, indirect labour, cost of sales, materials issued, sales returned, material returned, manufacturing overhead charged, and wages].

Accepted Answer

**This question cannot be solved as presented** — the transaction details are incomplete. The question statement lists transaction categories in brackets as placeholders: [detailed list of transactions including finished product, manufacturing overhead, raw material purchased, factory wages, indirect labour, cost of sales, materials issued, sales returned, material returned, manufacturing overhead charged, and wages] but does not provide the actual amounts or complete transaction data required for calculation.

Question 7

A factory uses job costing system. The following data are obtained from its books for the year ended 31st March, 2020: Direct materials ₹18,00,000; Direct wages ₹15,00,000; Selling and distribution overheads ₹10,50,000; Administration overheads ₹8,40,000; Factory overheads ₹9,00,000; Profit ₹12,18,000.

Accepted Answer

**Part (i): Job Cost Sheet for the Year Ended 31st March, 2020**

| Particulars | ₹ |
|---|---|
| Direct Materials | 18,00,000 |
| Direct Wages | 15,00,000 |
| **Prime Cost** | **33,00,000** |

| **Cost of Sales (Total Cost)** | **60,90,000** |
| Add: Profit | 12,18,000 |
| **Sales Value** | **73,08,000** |

**Part (ii): Pricing of the New Job**

Using previous year overhead rates:

**Factory Overhead Rate** = 60% of Direct Wages (₹9,00,000 / ₹15,00,000)

**Administration Overhead Rate** = 20% of Cost of Production (₹8,40,000 / ₹42,00,000)

**Selling & Distribution Overhead Rate** = 25% of Cost of Production (₹10,50,000 / ₹42,00,000), now increased by 15% → **28.75%** of Cost of Production

**Profit Rate on Sales** = ₹12,18,000 / ₹73,08,000 = **1/6 (16.67%) of Sales**

Question 8

Star Ltd. manufactures chemical solutions for the food processing industry. The manufacturing takes place in a number of processes and the company uses FIFO method to value work-in-process and finished goods. At the end of the last month, a fire occurred in the factory and destroyed some papers containing records. Opening work-in-process at the beginning of the month was 1,600 litres, 70% complete for labour and 60% complete for overheads, valued at ₹1,06,560. Closing work-in-process at the end of the month was 320 litres, 30% complete for labour and 20% complete for overheads. Normal loss is 10% of input and total losses during the month were 1,200 litres. Output sent to finished goods warehouse was 8,400 litres. Losses have a scrap value of ₹15 per litre. All raw materials are added at t…

Accepted Answer

**Part (i): Quantity of Raw Material Inputs**

Using the process account quantity balance under FIFO:

Opening WIP + Input = Output (Finished Goods) + Total Losses + Closing WIP

1,600 + Input = 8,400 + 1,200 + 320

Input = 9,920 − 1,600 = **8,320 litres**

---

**Part (ii): Normal Loss and Abnormal Loss**

**Normal Loss** = 10% of input = 10% × 8,320 = **832 litres**

**Abnormal Loss** = Total Losses − Normal Loss = 1,200 − 832 = **368 litres** (abnormal loss, not gain)

---

**Part (iii): Values of Raw Material, Labour and Overheads Added**

Under FIFO, equivalent units (EU) are computed only for work done in the current period.

**Equivalent Units — Raw Material (100% at start):**
Opening WIP completion (RM already 100% done, so 0% remains): 0
Units started & completed (8,400 − 1,600): 6,800 × 100% = 6,800
Abnormal Loss: 368 × 100% = 368
Closing WIP: 320 × 100% = 320
Total RM EU = **7,488 litres**

**Equivalent Units — Labour:**
Opening WIP (30% remaining): 1,600 × 30% = 480
Units started & completed: 6,800 × 100% = 6,800
Abnormal Loss: 368 × 100% = 368
Closing WIP: 320 × 30% = 96
Total Labour EU = **7,744 litres**

**Equivalent Units — Overheads:**
Opening WIP (40% remaining): 1,600 × 40% = 640
Units started & completed: 6,800 × 100% = 6,800
Abnormal Loss: 368 × 100% = 368
Closing WIP: 320 × 20% = 64
Total Overheads EU = **7,872 litres**

Scrap value of normal loss (credited against Raw Material cost since materials are added at commencement): 832 × ₹15 = ₹12,480

Question 10

ABC Ltd. had prepared the following estimation for the month of January: Material-A 800 kg at ₹90.00 = ₹72,000; Material-B 600 kg at ₹60.00 = ₹36,000; Skilled labour 1,000 hours at ₹75.00 = ₹75,000; Unskilled labour 800 hours at ₹44.00 = ₹35,200. Normal loss was expected to be 10% of total input materials and an idle labour time of 5% of expected labour hours was also estimated. At the end of the month the company has produced 1,480 kg finished product by using: Material-A 900 kg at ₹86.00 = ₹77,400; Material-B 650 kg at ₹65.00 = ₹42,250; Skilled labour 1,200 hours at ₹71.00 = ₹85,200; Unskilled labour 860 hours at ₹46.00 = ₹39,560.

Accepted Answer

**Standard Costing – Variance Analysis for ABC Ltd. (January)**

**Preliminary Standard Data:**
Total standard material input = 800 + 600 = **1,400 kg**. Normal loss = 10% × 1,400 = 140 kg. **Standard output = 1,260 kg**. Standard material cost = ₹72,000 + ₹36,000 = **₹1,08,000**. Standard labour hours = 1,000 + 800 = 1,800 hrs; idle time = 5% × 1,800 = 90 hrs; productive hrs = 1,710. Standard labour cost = ₹75,000 + ₹35,200 = **₹1,10,200**.

**Standard cost per kg of output:** Material = ₹1,08,000 ÷ 1,260 = ₹85.71/kg. Labour = ₹1,10,200 ÷ 1,260 = ₹87.46/kg.

**(a) Material Cost Variance (MCV):**
MCV = Standard cost for actual output − Actual cost
= (₹85.71 × 1,480) − ₹1,19,650
= ₹1,26,857.14 − ₹1,19,650 = **₹7,207.14 (Favourable)**

**(b) Material Price Variance (MPV):**
MPV = (Standard price − Actual price) × Actual quantity
Material-A: (90 − 86) × 900 = ₹3,600 (F)
Material-B: (60 − 65) × 650 = ₹3,250 (A)
**MPV = ₹350 (Favourable)**

**(c) Material Mix Variance (MMV):**
Actual total input = 900 + 650 = 1,550 kg. Standard proportion of 1,550 kg: A = 1,550 × 4/7 = 885.71 kg; B = 1,550 × 3/7 = 664.29 kg.
MMV = (Standard qty in std. proportion − Actual qty) × Standard price
Material-A: (885.71 − 900) × 90 = ₹1,285.71 (A)
Material-B: (664.29 − 650) × 60 = ₹857.14 (F)
**MMV = ₹428.57 (Adverse)**

**(d) Material Yield Variance (MYV):**
Standard yield from actual input = 1,550 × 90% = 1,395 kg. Actual yield = 1,480 kg.
MYV = (1,480 − 1,395) × ₹85.71 = 85 × ₹85.71 = **₹7,285.71 (Fav…

Question 11

A Ltd. manufacture and sales its product R-9. The following figures have been collected from cost records of last year for the product R-9: Direct Material 30% of Cost of Goods Sold; Direct Labour 15% of Cost of Goods Sold; Factory Overhead 10% of Cost of Goods Sold with Fixed Cost of ₹2,30,000; Administration Overhead 2% of Cost of Goods Sold with Fixed Cost of ₹71,000; Selling & Distribution Overhead 4% of Cost of Sales with Fixed Cost of ₹68,000. Last Year 5,000 units were sold at ₹185 per unit. Assume that Administration Overhead is related with production activity.

Accepted Answer

**Step 1: Identify Variable and Fixed Costs**

Given percentages represent variable cost elements as % of selling price:
- Selling price per unit: ₹185
- Variable cost per unit = (30% + 15% + 10% + 2% + 4%) × ₹185 = 61% × ₹185 = **₹112.85**
- Contribution margin per unit = ₹185 − ₹112.85 = **₹72.15**
- Contribution margin ratio = 72.15 ÷ 185 = **39%**

Fixed Costs (given in problem):
- Factory Overhead: ₹2,30,000
- Admin Overhead: ₹71,000 (production-related)
- S&D Overhead: ₹68,000
- **Total Fixed Costs = ₹3,69,000**

**Answer to Sub-parts:**

**(i) Break-even Sales = ₹9,46,154** (rounded)

Using formula: BE Sales = Fixed Costs ÷ CM Ratio = ₹3,69,000 ÷ 0.39 = ₹9,46,153.85

Alternatively, BE units = ₹3,69,000 ÷ ₹72.15 = 5,117 units (approx); Sales = 5,117 × ₹185 = ₹9,46,645

**(ii) Profit for Last Year = Loss of ₹8,250**

For 5,000 units sold:
- Total Sales = 5,000 × ₹185 = ₹9,25,000
- Total Contribution = 5,000 × ₹72.15 = ₹3,60,750
- Profit = ₹3,60,750 − ₹3,69,000 = **−₹8,250**

**(iii) Margin of Safety = −2.29%** (negative indicates operation below break-even)

MOS % = (Actual Sales − BE Sales) ÷ Actual Sales × 100%
= (₹9,25,000 − ₹9,46,154) ÷ ₹9,25,000 × 100%
= −₹21,154 ÷ ₹9,25,000 × 100% = **−2.29%**

The negative margin indicates the company is operating 2.29% below the break-even point, explaining the loss position.

**(iv) Profit if Sales 10% Less = Loss of ₹44,325**

With 10% reduction: Units sold = 4,500; Sales = 4,500 × ₹185 = ₹8,32,500

Question 12

A Vehicle manufacturer has prepared sales budget for the next few months: October 40,000; November 35,000; December 45,000; January 60,000; February 65,000 vehicles. To manufacture a vehicle a standard cost of ₹11,42,800 is incurred and sold through dealers at a uniform selling price of ₹17,14,200 to customers. Dealers are paid 15% commission on selling price. Four units of Part-X are required to manufacture a vehicle. The company holds stocks of Part-X at the end of each month to cover 40% of next month's production. 48,000 units of Part-X are in stock as on 1st October. There are 9,500 completed vehicles in stock as on 1st October and the company maintains stock at the end of each month to cover 20% of the next month's sales.

Accepted Answer

**Part (i): Production Budget (in nos.) — October to January**

Production = Sales + Closing Stock of Vehicles − Opening Stock of Vehicles

Closing stock of vehicles = **20% of next month's sales**

| | Oct | Nov | Dec | Jan |
|---|---|---|---|---|
| Sales (vehicles) | 40,000 | 35,000 | 45,000 | 60,000 |
| Add: Closing Stock | 7,000 | 9,000 | 12,000 | 13,000 |
| Less: Opening Stock | (9,500) | (7,000) | (9,000) | (12,000) |
| **Production** | **37,500** | **37,000** | **48,000** | **61,000** |

Closing stock derivation: Oct = 20% × 35,000 = 7,000; Nov = 20% × 45,000 = 9,000; Dec = 20% × 60,000 = 12,000; Jan = 20% × 65,000 = 13,000.

---

**Part (ii): Purchase Budget for Part-X (in units) — October to December**

Purchases = Production Requirement + Closing Stock of Part-X − Opening Stock of Part-X

Production Requirement = Production (vehicles) × 4 units
Closing Stock of Part-X = 40% × next month's production (vehicles) × 4 units

| | Oct | Nov | Dec |
|---|---|---|---|
| Production Requirement (×4) | 1,50,000 | 1,48,000 | 1,92,000 |
| Add: Closing Stock of Part-X | 59,200 | 76,800 | 97,600 |
| Less: Opening Stock of Part-X | (48,000) | (59,200) | (76,800) |
| **Purchases (units)** | **1,61,200** | **1,65,600** | **2,12,800** |

Closing stock derivation: Oct = 40% × 37,000 × 4 = 59,200; Nov = 40% × 48,000 × 4 = 76,800; Dec = 40% × 61,000 × 4 = 97,600.

Question 13

DIFFERENTIATE between Cost Accounting and Management Accounting.

Accepted Answer

**Cost Accounting** is the process of ascertaining, recording, and analyzing costs of products, services, or processes. It involves the identification, measurement, and allocation of costs to cost centers and cost units. **Management Accounting** is the application of accounting and costing techniques to the problems of management for strategic planning, control, and decision-making.

**Key Differences:**

**Scope:** Cost accounting has a narrower scope, focusing primarily on cost ascertainment and cost control. Management accounting has a broader scope, encompassing planning, control, decision-making, and strategic analysis.

**Nature and Orientation:** Cost accounting is historical in nature, dealing with costs already incurred and recorded. Management accounting is forward-looking, dealing with planning, budgeting, forecasting, and future decision scenarios.

**Objective:** Cost accounting aims to determine the accurate cost of products or services for inventory valuation, pricing decisions, and profit measurement. Management accounting aims to provide relevant and timely information to management for decision-making, planning, and strategy formulation.

**Statutory Requirement:** Cost accounting is mandatory under the Cost Accounting Records Rules for specified industries such as manufacturing, mining, and service sectors. Management accounting is not statutorily required and is entirely discretionary.

**User Base:** Cost accounting information is used by cost accountant…

Question 14

DISCUSS the impact of Information Technology (IT) on cost accounting system.

Accepted Answer

**Impact of Information Technology on Cost Accounting System**

**1. Real-Time Data Collection and Processing**
IT enables automatic capture of cost data from source transactions (production floor, materials, labor) as they occur. This eliminates manual recording delays and provides real-time visibility into cost elements, allowing managers to monitor costs continuously rather than through periodic reports. Barcode systems, RFID, and IoT devices feed data directly into cost systems, reducing human intervention and improving timeliness.

**2. Automation of Routine Cost Accounting Functions**
IT automates repetitive tasks including cost allocation, overhead absorption, inventory valuation, and standard costing calculations. Payroll integration automatically updates labor costs; production systems feed material consumption data; machine sensors record machine hours. This frees accountants from clerical work, enabling focus on analysis and interpretation rather than data entry.

**3. Enhanced Accuracy and Reduced Errors**
Automated systems minimize manual calculation errors in cost allocation, variance analysis, and reconciliation. Digital audit trails ensure data integrity. Once algorithms are correctly programmed, recurring processes execute with consistent accuracy. System validations catch data anomalies immediately, improving cost data reliability for decision-making.

**4. System Integration and Data Consolidation**
IT enables seamless integration of ERP systems connecting …

Question 15

DISCUSS the Escalation Clause in a Contract.

Accepted Answer

**Definition and Nature:** An escalation clause is a contractual provision that permits automatic adjustment of prices, payments, or other material terms based on predefined indices, cost changes, or specified events. It provides a mechanism to keep contract consideration aligned with changing economic circumstances during the contract period.

**Purpose and Need:** Escalation clauses address the fundamental issue of **price certainty** in long-term contracts. In contracts with extended performance periods, unforeseen changes in input costs, inflation, raw material prices, or labour costs can render fixed prices inequitable. The clause protects both parties: the supplier/service provider from bearing inflationary losses and the buyer from paying inflated prices if costs decrease. It ensures **fairness and sustainability** of contractual obligations over time.

**Types of Escalation Clauses:**

**Fixed Escalation:** A predetermined percentage increase (e.g., 5% per annum) applied at specified intervals regardless of actual cost movements.

**Index-Based Escalation:** Adjustment tied to recognized external indices such as Wholesale Price Index (WPI), Consumer Price Index (CPI), Labour Cost Index, or commodity-specific indices. This reflects actual market movements and provides objectivity.

**Cost-Plus Escalation:** Adjustment based on actual increase in specified cost components with supporting documentation. Common in contracts involving material costs, labour, or utilities.

Question 16

DISCUSS the treatment of by-product cost in cost accounting.

Accepted Answer

**By-products** are secondary products produced incidentally during the manufacture of main products and have relatively lower sales value compared to joint products. The treatment of by-product costs in cost accounting involves determining how much cost to allocate to by-products and how to reflect these in the final product cost.

**Key Methods of Treatment:**

**1. Net Realizable Value (NRV) or By-product Cost Recovery Method**: This is the most widely used method. The net selling value of by-products (selling price less any further processing and selling costs) is credited against the joint production cost, thereby reducing the cost of the main product. For example, if joint costs are ₹100,000 and by-product has NRV of ₹5,000, the main product cost is charged with ₹95,000. This method is logical because it recognizes that by-products contribute to recovery of joint costs.

**2. Reversal Costing Method**: Under this approach, the by-product revenue from actual sale is credited to the cost of the main product in the period of sale. The timing differs from NRV method—credit is given when actual sale occurs rather than at production. This reduces fluctuations but may result in cost matching issues.

**3. Absorption Method**: A portion of joint costs is allocated to by-products using a suitable allocation basis such as weight, volume, market value, or production hours. The allocated cost is then matched against by-product revenue. This method is less common for by-products but…
