If x is the median of the set {8/2, 11/3, 27/9, 21/5, x}, x could be
Choose the correct choice from the following:
A) 4	B) 17 / 5	C) 16 / 5	D) 30 / 7	E) 31 / 7

Rationale: the median is the middle number once all the numbers are arranged in increasing / decreasing order . we see that 11 / 3 = 3 . something , 28 / 9 = 3 . something 21 / 5 = 4 . something 9 / 2 = 4 . something so x should greater than the smallest two numbers and smaller than the greatest two numbers . we can see that x = 4 is possible . ( first look at the simplest option or the middle option since options are usually arranged in increasing / decreasing order ) answer ( a )
Answer: A
