The weights$(\mathrm{in} \mathrm{kg})$of $45$ students of a class are given in the following distribution table. Determine the value of weight $\mathrm{x}\left(\mathrm{kg}\right)$ which is such that the number of students having weight less than $\mathrm{x} \mathrm{kg}$ is same as the number of students having weight more than $\mathrm{x} \mathrm{kg}$.

Compute the median marks for the following data.
