Answer
Explanation:
Step1: Understand box - plot quartiles
In a box - plot, the left - most whisker represents the minimum value, the left side of the box represents the first quartile ($Q_1$), the middle line of the box represents the median ($Q_2$), the right side of the box represents the third quartile ($Q_3$), and the right - most whisker represents the maximum value. The first quartile ($Q_1$) marks the 25th percentile, meaning 25% of the data lies below it.
Step2: Locate $25$ on the box - plot
We observe that $25$ is at the first quartile ($Q_1$) of the box - plot.
Answer:
25
