Another great lecture. Just need to put it into practice now.
Sir, u r just amazing…. ur lectures are so intresting…. and wht else can i say… i just love opentuition…. thumbs up for u sir…. keep it up
Very helpful lecture. I was very lost when studying the text but this lecture cleared this up for me. Just need alot of practice now xD
Thanks, the lecture was very insightful!
Just a question though, at the end where you mentioned that shadow price for demand of E would be zero due to slack.
What if that was not the case and demand is 10, I was wondering how would the calculation or approach be like?
You would do it in exactly the same way as the others.
You would calculate the new optimum point if the demand limit was 1 more (i.e. 11) and the shadow price would be the extra contribution that would result.
Many thanks but is it possible to have an example for such a question? Can’t seem to visualize one from the current question
If you look again at example 1 in the chapter, but this time suppose the maximum demand for executive chairs was 4 (instead of 10).
The graph in the answer would stay the same except that the demand line would move to the left.
It will mean that the feasible area will be A, D, O, and the point where the demand line crosses the labour line. (The existing point B would no longer be feasible).
The new optimum point would be where the demand line crosses the labour line (which would be producing 4 executives and 32 standard chairs) and the new maximum contribution would be $312.
This time, the material constraint would be redundant (and the shadow cost of material would be zero). However the demand would be limiting – if we could increase the maximum demand by 1 unit then we could change the production and make more contribution. The extra contribution from having demand for 1 more unit would be the shadow price.
I think your video cover all the complex area of the syllabus. But I found your examples as easy than compare to examination level or even in Kit. After having lectures I need to study from the study text and go through the examples which takes lots of time. Even I dont get time to have Kit questions. This way I can only cover 1 or 2 topics per week.
The other question is that as I am very poor boy, so after completing my papers till f7. Will I be able to have any job? Which country do I go that is cheaper for students and can let me study with cheap costs and a job.
Is there any solution? By the way Opentuition is a miracle for me.
The lectures do cover what you need for the exam in terms of the technique. The examples that I go through are certainly enough in terms of the technique, but the wording is deliberately kept more simple than the wording in the exam (because I am trying to make sure people understand the technique). Also exam questions often examine more than one topic in the same question – I can only teach one topic at a time in lectures
On courses, after I have finished the lecture the class then work through some past exam questions.
If you look at the main Paper F5 page on this website you will find some lectures working through past exam questions – you might find this saves you time and saves you having to work through the Study Text so much.
I cannot really help with regards to jobs and with regard to countries with cheap costs etc.. A lot depends on which country you live in. Courses are pretty expensive everywhere
One question: The Point “B” that we gained, came from the simultaneous equation. I mean “2S+4E=80 and 5S+6E=180″. So why we used our graph for B? I mean if we simply could use this equation that was obvious from the question then why we need to put stress on graph? Then we cant certainly try the other farther points.
The problem is that if you did not have the graph then you would not know whether the optimal point was at point A, B, C or D. Depending on the angle of the objective/contribution line it could be any of them. Also, what about the point where the labour line crosses the demand line? This is not a feasible solution, but without the graph this would not be obvious.
Also, in the exam you will almost certainly be required to draw the graph – in which case you obviously have no choice. (And on at least one occasion the graph was given in the question – in this case you obviously were not required to draw it yourself, but you did need to know how to interpret it.)
ok. Thanks for the quick solution.
Good day to you I just started using opentuition for my study after June’13 exams. I thoroughly enjoyed your presentation in every chapter. Your delivery was so engaging. By any measure you are a very effective lecturer I appreciate your time, your patience and your ability to make a dry subject interesting Thank you so much, sir.
I have already started doing revision. I’m using the latest BPP revision kit. I have something not understand about Linear Programming. I stuck in questions 24 (Question 3, December 2010 exam). In part (a), after draw the graph, we need to find the optimal solution using iso-contribution line then solving the simultaneous equations for these constraints :
4x + 5y = 9,600 x 3
3x + 2y = 5,000 x 4
My questions is why we need to multiply the constraints by 3 for skilled labour constraints and multiply 4 for silk powder constraints? And why not multiply by 1 or 2? How we know when we need to multiply the constraints?
Once again, thank you for your time and for always going the extra mile as a lecturer. I appreciate it more than you will ever know
Enjoy your weekend
I guess the reason of multiply to 3 and 4 is to eliminate X
As a result (2-1): 7y=8800 ===> y=1257.1429…………….
Thanks. That’s mean as long as the number can eliminate X or Y then we multiply that number? Is it what you mean?
Thats correct – multiply by whatever numbers end up giving either the same number of X’s or the same number of Y’s in both equations. Then by subtracting one equation from the other either the X’s or the Y’s will disappear.
Thank you, sir and Koszhanov. Have a nice day
the video when played, says “404 not found”. how can I remedy this now?
Please visit the support page: http://opentuition.com/support/
Thank you open tuition. Thank you John Moffat
thank u a lot…the explanation was clear and get it right…:)
Thank u sooo sooo much teacher is great .
How well he explained everthing Respect from Pakistan.
very helpful in revision…thanks sir
Please what happened to the videos on revision of past exam questions? and the link on myacca for past exam papers doesnt seem to be opening as well!!!
All lectures based on F5 past exams are on this page: http://opentuition.com/acca/f5/f5-revision-kit/
acca updated their site with past exams- but links now should be working OK on opentuition.
Thank you very much.
admin can u tell me from where can I download these lectures???
You can watch them only on line
Is it necessary to read through the Student Accountant Articles? Please reply!
it’s a good idea not just to read, but actually understand those articles especially written by the examiner
Well done…pretty impressed.
Admin, the lecture has disappeared, there is no video at all!!!! and not just this lecture but all the lectures no longer contain a video, what it wrong?
The lectures are all still here and are working fine.
Admin can u plz tell me where can i find the shadow price article…..i did’nt find anywhere at website.thanks
The article was in the March 2008 edition of Student Accountant. You can find it on the ACCA website (under technical articles for F5)
Hello, can you please leave the link to the website where can I find the article about shadow prices etc. that you mentioned at the end of chapter 6?
Hi Mr. Moffat,
Stupid question here but I must ask it, what happens if I use “E” as the vertical axis?
Will the answer I derive be “correct” or no?
@marcp, it wouldn’t make any difference i think
It will not make any difference – the answer will be the same.
how can i download the videos am having difficulties
you can only watch lectures on line
am glad about opentuition
hello sir.. just a quick optimal point is always be where the labour and material cross each other or not can you help me for this please
Very good lecture………..
Thanks and it really made us very clear about linear..
They examiners articles are on the ACCA website, think there is a link on this website to the ACCA.
Clear Lecture, thank you so much
Lovely lecture indeed…was just asking how exactly i can get the link to an article by Jeff abt linear programming the lecturer talked about at the end of his lecture
johnmaft-is these notes enough for exams sir?
i bet people who ask these sort of questions haven’t even gone through all these video lectures..if you go one by one, you will see for yourself, how much this gets go..and you can make your own judgement if these are enough or not.
@sam2106, I totally agreee
@sweetusudu, The notes do not cover every single thing in the syllabus, but they cover more than enough to pass. HOWEVER, you will only pass if you practice lots of questions – certainly all the past real exam questions, and preferably using one of the Revision/Exam Kits that are available.
hai> sooooooooooo gud lect.i didnt hv any notes or relavant text buks for f5 and f6,bt i m gonna do exams this june.these lectures r understandable.is it enough for exams?and dnt they gve graph papers for exams.if nt we couldnt get the accurate optimal solution? anyone pls help me 2 clear my doubts.thnx a lot for lectures.plz reply me soon.
Great lecture, clear and really well explained. many thanks
is this person is the new lecturer of f5. what is his name and what he is doing. he is a superb teacher open tution.
@hassanzbilal, Thanks (but I am not new – it has always been me doing Paper F5 )
great effort by open tution that is very nice
@hassanzbilal, Thanks great lecture
i dont know what is happening to this beautiful lecture, part 2 linear its not playing.
Nice and clear lecture….he is superb! but could open-tuition go extra mile to make the iPhone apps for the site available for students who are mostly on the road….thanks a lot.
super lecture and thx
i didnt understand limit factors at first because we did not do it aat but after this lecture i understood it better..
The linear programing lecture is quite well explained.However, can some one help me understand why I have failed to download the subsequent lecture to example 1. Thanks a lot.
Now i understand that wat is the purpose of Shadow prices..:P
great lecture clear all the confusions
it was relly understandable. great job tanks much
i definitely owe opentuition a lot
thanks a lot
at what point in the lecture does shadow pricing start, also I want to start in the middle of the lecture but it would not load when I click the area i want to start from,only shows me time at the bottom and circle keeps spinning as if its loading but it never starts.
thank u so much. i know understand shodow pricing.
Very nice and helpful lectures,,, no need to take classes or tution from any institute, just sit at home and learn what you want
extremely clear and understandable lecture. great job!
My video cut out at 15:16 Hope it is back working tomorrow, these are great lectures!!
Its really helpful and many thanks to open tuition. Honestly i was confused in class but after this great lecture, my mind is clear. God bless U(contents to the Lecturer). What’s the name of the lecturer?
it’s gr8.. i would say, i don need to go to college to clear the topic.. opentuition would be more than enough…to clear the idea…thank u
thankyou so much for this lecture…WAS A GREAT HELP!!
great lecture,really appreciate this,now i know how to calculate the shadow price…………………….
having discovered the open tuition lectures, i can study on my own pace and they are great and clear. good explanation of the topic. can understand. thanks for the web site.
It is as gold for all business student. i have to be much interested in on line lectures. it is more helpful for all business student.i am most thankful for all ope tuition .com management.
You are the BEST lecturer.. I feel very motivated at the end of this..
THANK YOU VERY MUCH
very good lecture..thnkyou so much for the help
great work all of u there!
Thank you very very very much for your help!!!! You’re a great team! Everything is so clear.
clear great!!Thank you
this was a great lecture. easy to understand and well presented. before i couldnt understand shadow prices and now i totally do. thanks very much
The lecture flows and thats whats great about it ! it makes it easier to understand when the lecturer presents it well.
Hi there, this was helpful, however i am confused as to how 2 of the figures were calculated. They are:
$152.50 for labour
$22.50 for materials
I can’t see how were these figures calculated. Could anyone help?
HI MAN !
5s=181 – (6*4.75)
s=152.5/5 = 30.5.
5s + 10e = 202.5
0 + 4e = 22.5
e = 22.5/4 = 5.625.
hope it s not too late
Very helping…. thanks
thanks man……..great work.
