What does this mean??

Posted at: 2014-12-05 
seems to make sense. Lets just use 100,000 as the total income.

Out of the 100,000 the cost of the sold product was 50,000

all other expenses were 30,000

that leaves 20,000 as the operating income or profit.

on a document im told that the financial information is disguised, but the following is available;

cost if goods sold for FY 94/95 was 50 per cent

total other expenses for fy 94/95 were 30 per cent

operating income for the fy 94/95 was 20 per cent

this is for a division of the corporation, but i don't understand how these things can be given as percentages because the cost of goods sold and total other expenses are costs but the operating income is what's left after? and it looks as if they have been made to add up to 100 percent :/?
