Efficiency = input / output If expenses are $60 and revenue is $80 (perhaps net of interest revenue/expense) the efficiency ratio is 0.75 or 75% (60/80) â meaning that $0.75 are spent for every dollar earned in revenue.
As mentioned above a true antique is more than 100 years old, but some stores value furniture older than 50 years as antique and fine antique dealers will label items antique if they are more than 150 years old. The best way to find out is get the exact age of the piece.
The legal definition is that to be considered an antique, the item must be over 100 years old. In cars, over 25 years of age is considered antique. report this answer. Answered by kgb agent Jayson F on Wednesday, July 04 2012 at 05:21PM EDT. Source: antiquescollectibles.suite101.com/...
