Golda:
Both answers are wrong. You have to find geometric mean but you have calculated arithmetic mean. Also instead of finding mid range, you have calculated the median, which is different from mid range.

Solution:-
Geometric Mean -
x Log x
20 1.3010
25 1.3979
30 1.4771
45 1.6532
31 1.4914
36 1.5563
_____________________________________
N = 6 ∑ Logx = 8.8769
______________________________________
G.M. = Antilog (∑ Logx/N)
= Antilog 8.8769/6
= Antilog 1.4794
Geometric Mean = 30.16
Mid Range -
Mid Range = (Lowest value + Highest value)/2
Mid Range = (45+20)/2
Mid Range = 65/2
Mid Range = 32.5
