Sir, could you please kindly explain me the following. In workings to this problem the Incremental total hours are given. I can’t understand the purpose of this column. I understand the remaining part but can’t get the logic of this column. The previous column -Incremental number of batches is in fact number of batches for each month (actually the same as described in the problem) isn’t it?I also understand the figures, how they relate with each other, but I can’t get the meaning of this column. I think it’s essential to understand it.
The question asks for the cost for each month.
The doubling rule gives the total cost of all the months.
So, for example, we know the number of hours for July. The doubling rule gives the total hours for July and August together. So the hours for August are the difference between the total of July and August and the total for July.You are right that it is essential to understand, and I suggest that you watch my free lectures on the application of the doubling rule where this is explained.
Sir, I have listened to your lecture once more, and now I understand that column. Thank you for your lectures.
But, can you please tell me regarding the example in your lecture, where you demonstrate doubling rule, Total time for 8 units = 337.5, time for first is 100, the question is what is the time for extra 7. Here extra 7 is not the same as Total 7, yes? If we were asked to find out time for 7-th unit we would do it only using formula, right? I understand it as the following: extra 7 is units 2 till 8, and total 7 units and total 8 units are units1-7 and 1-8.
