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.
What is the most reliable car? Older cars, even ones considered classic cars, can also be labeled as antique. Antique cars are normally more than 45 years old and stay true to their original design as well. An old car that has been heavily modified may be considered vintage, but it can never be classic or antique.
