Question
A data has $25$ observations arranged in a descending order. Which observation represents the median$?$
✓
Answer
Number of observation $= n = 25 ($odd$)$
Hence, median $=$ value of $\Big(\frac{\text{n}+1}{2}\Big)^{\text{th}}$ observation
$=$ Value of $\Big(\frac{25+1}{2}\Big)^\text{th}$ observation
$=$ Value of $13^{th}$ observation
Hence, median $=$ value of $\Big(\frac{\text{n}+1}{2}\Big)^{\text{th}}$ observation
$=$ Value of $\Big(\frac{25+1}{2}\Big)^\text{th}$ observation
$=$ Value of $13^{th}$ observation

A small terrace at a football ground comprises of $15$ steps each of which is $50\ m$ long and built of solid concrete.
Each step has a rise of $\frac{1}{4}$m and a tread of $\frac{1}{2}$m. (see figure). Calculate the total volume of concrete required to build the terrace.
$[$Hint: Volume of concrete required to build the first step = $\frac 14 \times \frac 12 \times 50\ m^3]$
