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.
Classic car. This classification definitely overlaps with antique cars. The definition of classic car is actually quite similar to that of antique cars. A car must be at least 20 years old, but not more than 40 years old to be considered a classic car. It should again have been repaired and maintained in a way that keeps it true to its original design and specifications. In other words it should not be modified or altered.
