the answer is 24.5 by rounding off nearest tenth it becomes 25
PROCEDURE:
1: put all the numbers in numerical order i.e.22,23,24,24,25,26,28,29;
2:now the total amount of values is even, so the median will be the mean of two central values i.e.
(24+25)/2=24.5
now by rounding it off to nearest tenth it becomes 25
