I will answer your question with the attached histogram
Required
Determine the number of tall buildings that had more than 60 floors
The histogram can be interpreted as follows:
[tex]\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}[/tex]
More than 60 floors is represented with the following group: 61 - 80
The frequency of group 61 - 80 is 10
Hence, 10 buildings had more than 60 floors
