Question

At end of which year did the cumulative stock was the lowest?

• A. 2001
• B. 2006
• C. 2007
• D. 2010

Answer 1

The correct option is B 2006

According to the information given let us first see few formulas and then we can draw a table for revenues, profits, cash surplus and cumulative stock at end of each year.
Total production cost =Fixed Cost +(cost of each unit of body $\times 2$ $\times$ production ) +(Cost of each unit of engine $\times 3$ $\times$ production )
Total revenues =Selling Price $\times$ Sales
Cumulative Stock =(Cumulative Stock of previous year + Production -Sales)
Cash Surplus =(Cash Surplus of previous year + Revenue -Cost)
Also, they have a cash surplus of 10 million and there is no cumulative stock at the starting of the year 2001.
Note:
$CS\to$ Cumulative Stock (year end)
$TPC\to$ Total Production Cost (in millions)
$TSR\to$ Total Selling Revenues (in millions)
$TP\to$ Total Profit at end of year (in millions)
$CSP\to$ Cash Surplus (in millions)
