A manufacturing company uses rupees 50000 material per year the admini...
Solution:
Given information:
- Material cost per year = Rs. 50,000
- Administration cost per purchase = Rs. 50
- Carrying cost = 20% of the average inventory
- Optimum purchasing policy = ?
- Discount offered = 0.4%
- Number of purchases if discount is availed = 5
To determine whether the offer should be accepted or not, we need to calculate the total cost under the current policy and the cost under the new policy with the discount.
1. Cost under the current policy:
Let's assume the company's current policy is to make 'x' purchases in a year, and the average inventory held is 'I'. Then,
- Quantity purchased each time = (50000/x)
- Total cost of purchases = 50000
- Total administration cost = 50*x
- Average inventory held = I/2 (assuming constant rate of consumption throughout the year)
- Carrying cost = 20% of (50000/x) * I/2 = 5000I/x
Total cost under the current policy = 50000 + 50x + 5000I/x
2. Cost under the new policy with discount:
If the company avails the discount and makes 5 purchases in a year, then the quantity purchased each time would be (50000/5) = 10000.
- Total cost of purchases = 50000*(1-0.004) = 49800
- Total administration cost = 50*5 = 250
- Average inventory held = 10000/2 = 5000
- Carrying cost = 20% of 5000*I = 1000I
Total cost under the new policy with discount = 49800 + 250 + 1000I
3. Comparison of costs:
We need to compare the total cost under the current policy and the new policy with discount to decide whether the offer should be accepted or not.
Total cost under the current policy = 50000 + 50x + 5000I/x
Total cost under the new policy with discount = 49800 + 250 + 1000I
If the new policy is cheaper, then the company should accept the offer.
50000 + 50x + 5000I/x > 49800 + 250 + 1000I
Simplifying the inequality,
50x + 5000I/x - 1000I > 2050
Multiplying both sides by 'x',
50x^2 + 5000I - 1000Ix > 2050x
Rearranging the terms,
50x^2 - 2050x + 5000I > 1000Ix
Dividing both sides by 'x',
50x - 2050 + 5000I/x > 1000I
Therefore, if (50x - 2050 + 5000I/x) > 1000I, then the company should accept the offer.
4. Counter offer:
If the new policy with discount is not cheaper, then the company should negotiate a counter offer.
- One possible counter offer is to increase the discount percentage. The company can calculate the minimum discount percentage required to make the new policy cheaper than the current policy.
- Another counter offer is to increase the number of

Let cost per article is rs 1
so annual consumption will be 50000/1=50000
ordering cost= 50 rs
carrying cost is 20% so:1* 20/100=0.20
because carrying cost always charged on price of per material.
e.o.q= √2co/√i
√2*50000*50/√0.20
=5000
no.of order to be placed= c/e.o.q
= 50000/5000=10 orders
