Heights of $\displaystyle 50$ students of class X of a school are recorded and following data is obtained :
Find the median height of the students. Question Numbers from $\displaystyle 11$ to $\displaystyle 14$ carry $\displaystyle 4$ marks each.
| Height (in cm) : | $\displaystyle 130$-$\displaystyle 135$ | $\displaystyle 135$-$\displaystyle 140$ | $\displaystyle 140$-$\displaystyle 145$ | $\displaystyle 145$-$\displaystyle 150$ | $\displaystyle 150$-$\displaystyle 155$ | $\displaystyle 155$-$\displaystyle 160$ |
| Number of Students : | $\displaystyle 4$ | $\displaystyle 11$ | $\displaystyle 12$ | $\displaystyle 7$ | $\displaystyle 10$ | $\displaystyle 6$ |
Marking-scheme solution
| Class | $\displaystyle f$ | cf |
| $\displaystyle 130$-$\displaystyle 135$ | $\displaystyle 4$ | $\displaystyle 4$ |
