can you please explain to me the answer for the 3rd question. as per the formula EOQ= sqrt( 9000 x 160) / 3.2 the answer is A 671 but the result shows answer 3 how?
March 22, 2022 at 7:37 pm
no problem got the answer right in the second time around. was making a mistake in the formula.

Dear Sir. Please I do not understand the logic in question 2 of chapter four. If Inventory ordering cost to be decrease we have to order more inventory for decreasing the frequency of ordering. If we do so our level of inventory should increase as a result holding cost increases but the answer stats both EOQ & Holding cost declines Thank you very much for usual cooperation!!
February 17, 2022 at 5:46 am
If you look at the formula, then if Co is lower the EOQ will be lower to. (We will be placing more orders to get the same quantity in total, which makes sense because the cost of ordering each time is lower)
If the EOQ is lower then the average inventory is also lower and therefore the annual holding cost will be lower as well.
January 10, 2022 at 7:48 pm
Hello dear, I have not quite get Q2. Now if ordering costs are decreasing, it means we make fewer orders, therefore higher quantities of inventory are held each time. Doesn’t this mean holding costs are increasing? Please answer my question.
January 11, 2022 at 8:39 am
No – it is the other way round. If the order cost each time is lower then they will end up making more orders and a lower order quantity each time.
The best way to convince yourself it to take one of the examples from our notes, then repeat it with a lower order cost each time and see what happens to the EOQ and the annual holding cost.

Many thanks for this clarification

Good day sir In Chapter 4, question 1 How do you arrive at 1,461 as the answer Why is Demand of 20,000 multiplied by 4
January 20, 2023 at 6:24 am
Because the demand is 20,000 in 3 months and there are 4 lots of three months in a year.
January 20, 2023 at 11:18 am
Many thanks I now understand
January 20, 2023 at 1:58 pm
You are welcome 🙂
November 24, 2021 at 3:50 pm
Hi John Thanks for your Many Help but Question one is troubling me. Please where did 2 come from. My solution would have been below:
Purchase Price = $25 3 Month demand = 20,000 Annual Demand = 20,000 X 4 = 80,000 Cost of order = 20 Cost of holding = 6% of $25 = 1.5 Therefore, EOC = square root of (80,000 X $20)/ 1.5 = 1,032.80
please where did i get it wrong?
November 24, 2021 at 4:03 pm
Have you checked the formula? The numerator in the formula has a 2 in it 🙂
June 6, 2021 at 1:34 pm
Dear John, there is mathematical error in your calculation for question 1.
EOQ Units= 730
but your suggested answers says 1461 units
June 6, 2021 at 1:35 pm
Never mind ignored the requirement. your answer is correct
June 6, 2021 at 4:01 pm
I am pleased that it is correct 🙂
November 30, 2019 at 6:40 pm
If compared the response in Question 2 with example 1 done by you in Chapter 1, I understand vice-versa. So, in example 1 as per calculation we have increase in EOQ(from 500 units to 750 units), that lead to decrease in ordering cost, and respectively the increase in holding costs. From the graph in this chapter i understand that if cost of ordering decreases this lead to increase in holding costs and so on. Can you please explain me what am thinking wrong? Thanks in advance 🙂
November 1, 2019 at 7:29 am
Thanks John. Helpful questions more so with the calculation of the demand and the holding cost.
November 1, 2019 at 9:06 am
Thank you for your comment 🙂
September 3, 2019 at 10:34 am
thanks for the questions sir. but i have a bit of a problem with how Co affects holding costs. i initially assumed Ch as the holding costs and thought they do not have any effect on the Co
September 3, 2019 at 1:49 pm
I guess you are asking about question 2? If so, then Ch is the holding cost per unit and the question asks what will happen to the total holding cost per year.
If the order cost decreases, then the EOQ decreases. If the EOQ decreases then the average inventory decreases and therefore the total holding cost per year decreases.
July 19, 2019 at 8:33 am
hii john sir , i want to ask that in fm exam , this types of mcq/questions comes or similarly to this or way different that this?
July 19, 2019 at 2:21 pm
Questions in Section A are similar, but these are just meant to be short, quick tests.
You must buy a Revision Kit from one of the ACCA Approved Publishers – they are full of past exam (and other exam-standard) questions.
July 20, 2019 at 5:37 am
Thank you John sir ??

November 23, 2018 at 7:53 am
hi, help plz
consider on your study notes, Chapter 4 example 3, can you help me on how to find stock holding cost ?
November 23, 2018 at 8:49 am
Example 3 says to use the information given in Example 1.
You should only be using the lecture notes if you are watching the lectures. It is in the lectures that I explain and expand on the notes (and I work through this example in the lectures). If you are not watching the lectures for any reason then you must buy a Study Text from one of the ACCA approved publishers and study from there.
August 28, 2018 at 3:20 pm
For the annual demand, is it always in quantities? or can I say Annual Demand = Annual Sales?
August 28, 2018 at 7:23 pm
You always need annual demand in units for the formula, because the EOQ is always in units.
May 27, 2018 at 12:15 pm
I am confused about F9 chapter 4 question 2. I thought EOQ will increase when ordering cost decreases. The formulae even proved my point. But I stand to be corrected. Can you pls clarify that a bit?
May 27, 2018 at 5:41 pm
The formula certainly does not prove your point!!!
The ordering cost appears as part of the numerator in the formula. If it decreases then so to does the EOQ.
(I assume you watched the free lectures on this before attempting the test? The lectures are a complete free course for Paper F9 and cover everything needed to be able to pass the exam well.)

Hello. I was just revising all these chapters by doing these practise questions. They’re really helpful . But question 5 of this question says that JIT approach may lead to more inventory shortages. But from what we’ve learnt from the lectures and notes. JIT ,tries to make sure there r no shortages of inventory when we need them by either getting suppliers to supply immeditaly and by training the working. So with this approach. Jit shouldn’t really cause of problem with inventory shortages right?
November 28, 2017 at 1:47 pm
But there is still a bigger risk of inventory shortages – however well JIT is organised, something may still go wrong 🙂
August 18, 2019 at 7:45 pm
To add to what John Moffat said, assume the supplier has sent out the order but the delivery van develops a fault on the way. This would mean the client could ran out of inventory for the hours or days required to fix the van or arrange alternative transportation. That’s the risk in JIT … you have no buffer to fall on!
August 26, 2017 at 9:44 am
Hello. As part of the study programme, I want to complete the Past Exam Question (Specimen Q1) however, Q1 does not seem to have anything to do with “Management of Working Capital – Inventory”. Am I misunderstanding the study programme/the actual question or is it incorrect?
August 26, 2017 at 10:10 am
Please ask this in the Ask the Tutor Forum, and not as a comment on a practice test!
April 2, 2017 at 12:29 pm
why working examples have no answers to check against mine I have worked out to make sure everything is 100% correct. Even some are straight forward but it is to maximise marks as much as possible
April 2, 2017 at 2:54 pm
If you are talking about answers to the questions in this test, then a pop-up window appears with the answer and workings when you submit your answer. Maybe you have a pop-up blocker, in which case you should turn it off!!
(If you are talking about answers to the examples in the lecture notes, then the answers are all in the lecture notes. Also I work through all the example in the free lectures that go with the notes, and it is completely pointless to use the notes without watching the lectures that go with them.)
September 27, 2016 at 11:22 pm
These questions are a great help
September 28, 2016 at 3:16 am
That is good to hear 🙂
(I hope that you are watching the free lectures also – they are a complete course for Paper F9 and cover everything needed to be able to pass the exam well.)
September 28, 2016 at 8:58 am
I am working my way through the lectures and then answering the questions, they put everything i have just learnt into practice.

April 28, 2019 at 8:01 pm
Hi John how are we arriving to EOQ OF 945 in question 3
April 28, 2019 at 8:03 pm
April 29, 2019 at 1:56 pm
We use the EOQ formula as I explain in the free lecture.
D = 9,000 per year; Co = 160; and Ch = 8% x $40 = 3.20
June 1, 2017 at 5:24 pm
As we know the D in the EOQ formula means one period.That not means per annum demand. So why in the two above questions where the demand was in 3 months time but we had to multiply 3 with 4 to get the annual demand?
June 1, 2017 at 5:53 pm
Use any period you want, but the prior used for the demand must be the period used for the stockholding cost (Ch). So by all means use the 3 month demand, but also use the 3 month Ch. You will end up with exactly the same answer!!!
June 2, 2017 at 8:52 am
You are saying because the cost of holding one unit is per annum so the demand must related likewise?
June 3, 2017 at 5:04 pm
ok i got i tired it and got exactly the same answer.Thanks
June 3, 2017 at 5:25 pm
