Hi, I would like to know whether it is advisable to have long length of workings? Will I gain more marks to have a longer workings or the marks will be equal as long as the answer is correct?
I would take Pilot Paper Q4 : DIY for example as I will use different formula.
This is my answer compare to the examiner answer:
Formula => WACCg = WACCu x [1- (Dt/E+D)]
Degeared: 6.8 = WACCu x [1- (0.5x.03)/(3.5)} WACCu = 7.1 (same as Ke answer in the pilot paper)
It does not matter how long or short the workings are.
The main thing is that is should be clear what you are trying to do. Provided it is clear then you will get most of the marks whether your final answer is right or wrong.
Your answer above is fine and would get full marks.
