Explanation:

Step1: Identify quartiles from box - plot

The box in a box - plot represents the inter - quartile range. The lower end of the box is the first quartile ($Q_1$) and the upper end is the third quartile ($Q_3$). From the box - plot, assume $Q_1 = 65$ and $Q_3=75$.

Step2: Calculate the IQR

The formula for the inter - quartile range is $IQR=Q_3 - Q_1$. Substitute $Q_1 = 65$ and $Q_3 = 75$ into the formula. So, $IQR=75 - 65=10$.
