How does a calculator work?

How can i work out Gross Profit and percentages without using a calculator? Please can some one help?

• I have a test for a job coming up and they require you to work out gross profit and percentages without using a calculator.. I have always used a calculator for things like this. Please please can some one help and give me some tips to do this. I really want this job and this is the final part, and if I fail this I don't get the job. I would be so so grateful.

• Answer:

  Profit = Revenue - Costs To calculate other figures as a percentage of gross profit, divide that figure by gross profit. My guess is that since they don't want you to use a calculator, the calculations won't be too complex. Example: Gross Profit = 1,000,000 Cost of Goods Sold = 100,000 COGS as a % of Gross Profit = 100,000/1,000,000 = 0.10 or 10% An easy way to visualize any percentage calculation and solve it manually is to set it up like x%/100 = [figure]/[whole] In the example above, it would be x%/100 = COGS/Gross Profit x%/100 = 100,000/1,000,000 1,000,000(x%) = 100,000(100) 1,000,000(x%) = 10,000,000 x% = 10,000,000/1,000,000 x% = 10% Good luck!
