The median of the observations is the value that is in the middle of the data.
The cumulative frequency of the given data is shown below:

Here, n=100(even).
The formula for median if n is even is:

median = \frac{\frac{n}{2} t h term + (\frac{n}{2} + 1) t h term}{2}

So, median is the mean of

\frac{100}{2} t h and \frac{100}{2} + 1 t h terms

observations, or 50th, and 51st observations.
The 50th term from given data is 4100 and 51st term is 4500 as per table of cumulative frequency.
Hence, median =

\frac{4100 + 4500}{2}

\Rightarrow median = \frac{8600}{2}

\Rightarrow median = 4300

Therefore, the median wage of a worker at a construction site is Rs. 4300.
Hence, option 2 is the correct answer.
