If x and y represent the mean and the median respectively of the following set of numbers 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, find the (frac{x}{y}) correct to one decimal place

A.
18 
B.
15 
C.
1.0 
D.
5
Correct Answer: Option C
Explanation
Mean (bar{x}) = (frac{156}{10}) = 15.6
Median = (bar{y}) = (frac{15 + 16}{2})
(frac{31}{2}) = 15.5
(frac{x}{y}) = (frac{15.6}{15.5}) = 1.0065
