Q22:

At a garage sale, all of the prices of the items sold were different.  If the price of a radio sold at the garage sale was both the 15th highest price and the 20th lowest price among the prices of the items sold, how many items were sold at the garage sale?

A.     33

B.     34

C.     35

D.     36

E.      37

The answer is B, why not C?

第一题的graph没有，不能解吧，呵呵。

第二题，LZ想想看，您可能多算了一个，radio的后面有19个，因为它是第20低，前面有14个，因为它是第15高，所以算上它自己，一共是19+14+1=34个，对吧，加油！

谢谢
