_____ is equal to the value corresponding to cumulative frequency (N+1)/4 from simple frequency distribution

The mean of a data set comprising of $\mathrm{16}$ observations is $\mathrm{16}$. If one of the observation value $\mathrm{16}$ is deleted and three new observations valued $3,\; 4$ and $\mathrm{5}$ are added to the data, then the mean of the resultant data is

 $40$ 40 students enter for a game of shot-put competition. The distance thrown (in metres) is recorded below:

Use  a graph paper to draw  an ogive for the above distribution.

Use a scale of $2 cm=1m$ on one axis and $2 cm=5$ students on the other axis. Hence using graph find Upper Quartile.
