Hi Sir,

I am going through the December 2013 Q3a and wanted to double check something with you.

Whenever I see Actual Total Monthly or something similar does that mean that the examiner want us to use a Table to show our answers (as is showing on the answer sheet found online)?

Thanks

November 22, 2015 at 4:39 pm #284626It doesn’t matter how you show your workings (it certainly doesn’t need to be a table) provided that your final answers obviously stand out, and also that you do show your workings (because marks are given for the workings and you will get them if your workings are the right way, even if you make an arithmetic mistake and the final figure is wrong).

It doesn’t matter whether you use the doubling rule (as the examiners answer does) or whether you use the formula on the formula sheet – both ways will give the same answer (except maybe a bit of rounding difference, but that doesn’t matter). If you do choose to use the formula, then again you must still show your workings and not simply an answer from your calculator.

In part (a) I actually think that using the doubling rule is quicker and easier, but that it up to you and again it does not matter.

However, do make sure that you can use the doubling rule. Not in this question, but in some other questions the examiner has specifically asked for you to use the doubling rule and then you would obviously lose marks if you didn’t 🙂

(If you are unsure about the doubling rule, then please do watch my free lecture which goes through both the rule and the formula. Our lectures are a complete course for Paper F5 and cover everything you need to be able to pass the exam well 🙂 )

November 25, 2015 at 4:39 pm #285238Help I need help on some questions

Q1 – Company produces new product: first took 18 hours to complete, second took 10 hours to complete – What is the learning rate?

November 25, 2015 at 5:19 pm #285262The average time per unit to produce 2 units is (18 + 10) /2 = 14 hours.

Therefore the learning rate is 14/18 = 0.78 (or 78%).

I do suggest that you watch our free lecture on this because I work through a very similar example.
