Just in case you aren't pulling my leg-

What about this:
You have two bank accounts-

First bank a/c had $100 in it, you earn $10 interest and have a balance of $110 at the end of the FY.

Second bank a/c had $100,000 in it, you earned $5,000 interest and have a balance of $105,000 at the end of the FY.

Dollar wise, one a/c went up by 10 and the other by 5000.

Which bank a/c performed the best and gave you the best return for your money and which method did you use to calculate the result?
