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 Antiques Roadshow must regularly decide what is and what is not an antique. According to them, an antique is, [g]enerally speaking, an object of considerable age valued for its aesthetic or historical significance. In the antiques trade, the term refers to objects more than 100 years old.. Thus, when buying or selling an item labeled antique, trade standards suggest that the term should be reserved only for items greater than 100 years old. Outside of the practice of buying and selling items, however, use of the word antique can be understood to attach no specific age to an item.
