Case Scenario – I:
Skylark Electronics Company assembles and sells laptops in India. An important component of laptop is its rechargeable battery. The company buys its monthly requirement of 4,500 batteries and it would buy its annual requirement in 10 equal instalments. The purchase cost of one battery is ₹ 800.
The batteries are used evenly throughout the year in the assembling process on 360 days per year. The ordering cost is ₹ 9,000 per order and the inventory carrying cost is 37.50% per annum. The high carrying cost results from the need to keep the batteries in carefully controlled temperature under humid conditions along with high cost of insurance.
Delivery of the batteries from the vendor generally takes 6 days but it may go up to as much as 10 days. The days of delivery time and percentage of their occurrence are shown in the table below:
Delivery Time (Days) |
6 |
7 |
8 |
9 |
10 |
Percentage of Occurrence (%) |
70 |
15 |

On the basis of above case scenario, you are required to answer the following MCQs 1 to 5:
1. At what quantity of purchase of batteries, the ordering costs will be equal to the inventory carrying costs?
(A) 1600
(B) 1700
(C) 1800
(D) 1900
To find the quantity at which ordering cost = carrying cost, we use the Economic Order Quantity (EOQ) formula. At EOQ, Ordering Cost equals Carrying Cost.
Given:
EOQ Formula:
EOQ = √(2DS / H)
= √(2 × 54000 × 9000 / 300)
= √(972000000 / 300)
= √3240000
2. What will be the total annual cost of purchases as per the quantity calculated in Q-1 above?
(A) ₹ 3,84,80,000
(B) ₹ 4,37,40,000
(C) ₹ 4,29,30,000
(D) ₹ 5,80,84,000
This includes the purchase cost, ordering cost, and carrying cost as per the EOQ calculated in Question 1 (1,800 units).
Given:
Formula:
Total Cost = (D × P) + (D/Q × S) + (Q/2 × H)
= (54,000 × 800) + (54,000 / 1,800 × 9,000) + (1,800 / 2 × 300)
= 43,200,000 + 270,000 + 270,000
3. Assuming that the company is willing to take a 15% risk of being out of stock, what would be the safety stock and the Re-order point?
(A) Safety stock 1050 batteries and Re-order point 2250 batteries
(B) Safety stock 2250 batteries and Re-order point 1050 batteries
(C) Safety stock 1450 batteries and Re-order point 2850 batteries
(D) Safety stock 1250 batteries and Re-order point 2650 batteries
At 85% service level (15% risk), cumulative demand during lead time is 2250 batteries.
Expected demand = 1200 → Safety stock = 2250 - 1200 = 1050 batteries.
4. Assuming that the company is willing to take a 5% risk of being out of stock, what would be the safety stock and Re-order point?
(A) Safety stock 1100 batteries and Re-order point 2800 batteries
(B) Safety stock 1350 batteries and Re-order point 2550 batteries
(C) Safety stock 1280 batteries and Re-order point 2900 batteries
(D) Safety stock 1550 batteries and Re-order point 3280 batteries
5. Assuming 5% risk of out of stock what would be the total cost of ordering and carrying inventory for one year?
(A) ₹ 5,40,000
(B) ₹ 8,15,000
(C) ₹ 9,45,000
(D) ₹ 10,80,000
Total Cost = (D/Q × S) + ((Q/2 + Safety Stock) × H)
Given:
Calculation:
Total Cost = ₹2,70,000 + ₹6,75,000 = ₹9,45,000
Case Scenario – II:
Allure Metallurgy Ltd. is a stainless-steel manufacturing company which manufactures two grades of stainless steel products namely SS304 & SS316 made of a common raw material iron procured at ₹52 per kg from the market. The usage of the raw material is expected to be at a constant rate over the entire period.
The raw material supplier to the company charges ₹24,000 per order but its delivery is limited to 1200 tons per annum. There is no alternate source to procure the raw material. In consideration of the above limitations, the company decided to review its inventory management policies for the forthcoming year.
The following forecasted information has been extracted from departmental estimates for the budget year ending on 31st March 2025:
|
SS304 |
SS316 |
Sales (units) |
56,000 |
86,000 |
Finished Goods stock increase by year end (units) |
1,614 |
1,215 |
Post Production rejection rate (%) |
3 |
7 |
Iron usage in kg (per completed unit, net of wastage) |
5.5 |
8 |
Iron wastage (%) |
8 |
11 |
You are required to calculate the following (MCQ’s 6 to 10):

For SS304:
Production = (56,000 + 1,614) / 0.97 ≈ 59,396
For SS316:
Production = (86,000 + 1,215) / 0.93 ≈ 93,780
7. The ratio in which the raw material utilized for SS304 & SS316 from the total quantity of raw material procured, to produce the number of units desired in Q-6 above?
(A) 29.59% & 70.24%
(B) 29.64% & 70.36%
(C) 30.33% & 69.67%
(D) 38.77% & 61.23%

(A) 7,50,240 kg
(B) 7,51,460 kg
(C) 8,42,966 kg
(D) 8,44,337 kg
Given:
Calculation:
SS316 Material Requirement = 1,200,000 × 0.7036 = 844,320 kg
