ROI

another question on ROI a company has 3 asset and all of them have opening and closing value, So when calculating ROI should i choose "average value" or "closing value" of this asset as capital employed......?????

There is no rule - either in the exam or in 'real-life'. There are arguments for using the opening value or the closing value or the average value. Usually in the exam the question will either tell what to use, or else will only have information about either the opening or the closing value (in which case you obviously have no choice). If it is not clear from the question then you would get the marks whichever you used. (The opening value is usually the better one on the basis that it is the value at the start of the year that generate the profits for the year, but again this is not a rule)

How to measuring divisional manager performance when "Head office has increased wages pay of all division by 15%" should i exclude whole wages cost or only the 15% in calculating ROI

and ROI is measured based on controllable profit

Actually i am trying to say that if head office increase any of the cost of division which are controllable by manager, then how am i going to treat this increase when calculating ROI ROI is measured by controllable profit

You would ignore the wages completely because they are no longer under the control of the division.

So this techniques will apply to all cost changed by the head office no matter cost is controlled by manager or not

If they are changed by head office then the manager no longer controls them.

Thank u sir

You are welcome :-)
