Study the sector wise sales of a group of companies for the financial year 2004 - 2005 and answer the following questions.
The average profit against the sales across the sectors is 10% while the profit margin of engineering is 12% and CIS, 20%. What is the average profit across the remaining sectors?
Let us represent the sales revenue in terms of 'k'.
Total sales revenue = 100k
Sales revenue from Engineering = 31k
Sales revenue from CIS = 19k
Remaining revenue from other sectors = 50k
Profit margin = Profit/Revenue
Let the profit margin of remaining sectors be x%.
So the eqn is:
10*100k = x*50k + 12*31k + 20*19k
after cancelling 'k' from both sides, we get:
=> x = 4.94% (answer)
