Solution

The answer is C.
First, we arrange the given numbers in ascending order as,
3, 4, 4, 5, 6, 7, 7, 7 and 12.
Here, n = 9
Since n is odd, we use the formula for the median.
Now,
$m e d i a n = (\frac{n + 1}{2})$ th observation
$= (\frac{9 + 1}{2})$ th observation
$= (\frac{10}{2})$ th observation = 5th observation = 6
Hence, median of the given numbers is 6.
