If x is the median of the set {9/2, 10/3, 27/9, 21/5, x}, x could be Options:
A) 16/5  B) 17/5  C) 28/7  D) 30/7  E) 31/7
The median is the middle number once all the numbers are arranged in increasing/decreasing order.   We see that   10/3 = 3.something,   27/9=

<output>3</output>
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 (28/7)
