Explanation:

Step1: Recall box - whisker plot components

In a box - and - whisker plot, the box has three important lines: the left - most line of the box represents the first quartile ($Q_1$), the middle line represents the median ($Q_2$), and the right - most line of the box represents the third quartile ($Q_3$). The whiskers extend from the box to the minimum and maximum values of the data set.

Step2: Identify the first quartile from the plot

Looking at the given box - and - whisker plot, the left - hand side of the box (the line that marks the start of the box) is at the value of 50. So, by the definition of the first quartile in a box - and - whisker plot, the first quartile ($Q_1$) is 50.

Answer:

50
