Question

Below is the histogram of number of people in the age range from 1 – 25 years. How many people are younger than 17 years?

(a) 16

(b) 23

(c) 47

(d) 63

I have been asked this question during an interview.

This interesting question is from Data Handling topic in division Data Handling of Mathematics – Class 8

Answer 1

Right choice is (d) 63

For explanation I would say: The height of the bar represents the number of data items in the given data range called frequency. The number of people younger than 17 years is sum of number of people between 1-5, 5-9, 9-13 and 13-17 which gives us 63.
