我也觉得是A。

monacopig

market value = purchasing price ?

yzhao26

should B

Purchasing price is not equal Marketing value.

Depreciated is term for accounting which means from A can know book value, not marketing value

therefore should B is right

monacopig

Since market value=/= purchasing price, then the answer should be E, neither 1 nor 2 is sufficient.

Statement 1 says the market value of the car depreciated by 20% of its “Purchase Price” per year. However, we do not know what the “Purchase Price” of the car was. We know its “Market Value” was $6000. But we don’t know at what price it was purchased. So Statement 1 alone can not determine the current market value of the car.

 

Statement 2 says that the current market value of “a car” manufactured in the same year is $2400. There are many types of car manufactured in the same year as “the car”. This statement indicates the value of just one of those types of cars, but not necessarily all of them. So this statement is also insufficient on its own to indicate the current market value of the car.

 

The two statements together also do not indicate the present value of the car.
