Total no of days = 5+11+8+6=30
median when n is even = sum of middle two terms/2 = (n15+n16)/2
n15=30
n16=30
median =30

Corrected !!

Ans: B
total no. of days.. = 30 days so median will be avg of 15th and 16th term of set [ 29 (5 times) 30 (11 times) 31 (8 times) 32(6 times)]
15th term = 30 and 16th terms =30
so median = 30
