Measurements of some variable X were made at an interval of $ 1 $ minute from $10 text A.M. to 10:20 text A.M. $. The data, thus, obtained is as follows:
$ X : 60, 62, 65, 64, 63, 61, 66, 65, 70, 68, 63, 62, 64, 69, 65, 64, 66, 67, 66, 64 ,50.$
The value of $X$ which is exceeded $50 %$ of the time in the duration of measurement, is
$(i) 69 \ (ii) 68 \ (iii) 67 \ (iv) 66 $
Answer:
It is a multiple choice question and it is general knowledge question.
The answer is $ 68 $.
But I am unable to understand the question. What exactly says the question?

I don't understand it either. The value $68$ is only exceeded twice (by the values $69$ and $70$,) which is $10%$ not $50%.$ Are you certain all these numbers are correct? -- Oops it's $2/21$ not $2/20$ so a bit less than $10%$.

With the given data, $$X : 60, 62, 65, 64, 63, 61, 66, 65, 70, 68, 63, 62, 64, 69, 65, 64, 66, 67, 66, 64 ,50$$
$68$ is the data collected at 10:10 which is the middle of time interval $10:00 $ to $10:20$
That is the only interpretation which makes the answer $68$ otherwise, $68$ is not the median of your data at all.

To add to this: The median (which the question somehow seems to try to ask for) would be 64, which is not even among the available choices.

Isn't the question maybe written badly? I could think the author meant:
The value of X at which 50% of the time in the duration of measurement is exceeded
Clearly if this is an exam question, I would definitely consider the question as void, as it is unclear.
