firstly arrange this data in ascending order
15, 16, 16, 19, 25, 28, 28, 32, 36, 40, 40, 42.
total no element are 12 (even no )
(n/2)th= 12/2 = 6th position
(n/2+1)th = 6 + 1 = 7th position
median = ((n/2)th + (n/2+1)th) / 2
= (6th position + 7th position) / 2
= 28 + 28 / 2
= 56 / 2
The median of data = 28
HOPE THIS HELPS
