Solution:
Given:
The ages in years of the 10 professors at a college to be;
44,38,45,34,28,56,54,28,61,48
Professors who are younger than 47 = 44,38,45,34,28,28
Number of Professors who are younger than 47 = 6
The percentage of these professors who is younger than 47 =
[tex]\begin{gathered} =\frac{6}{10}\text{ x 100} \\ =60\text{ \%} \end{gathered}[/tex]Therefore, the percentage of professors who is younger than 47 is 60%
