I got this question in an internship interview.

The question is from Data Handling in chapter Data Handling of Mathematics – Class 8

Answer 1

The correct option is (a) 37

Explanation: The height of the bar represents the number of data items in the given data range called frequency. The number of people older than 13 and younger than 25 years is sum of number of people between 13-17, 17-21, 21-25 which gives us 37.
