The following histogram shows the monthly wages (in ₹ ) of workers in a factory: In which wage-group the largest number of workers are being kept? What is their number?

In the given figure, the highest rectangle corresponds to the largest number of workers. The interval in which the largest number of workers are being kept is 950 − 1000 . There are 8 workers in this interval.

The following histogram shows the monthly wages (in ₹ ) of workers in a factory: What wages are the least number of workers getting? What is the number of such workers?

The following histogram shows the monthly wages (in ₹ ) of workers in a factory: To find: What wages are the least number of workers getting and number of such workers. The lowest rectangle corresponds to the least number of workers. The required interval is Rs 900 − 950 . There are 2 workers in this interval.

The following histogram shows the frequency distribution f the ages of 22 teachers in a school: What is the number of eldest and youngest teachers in the school?

In the given figure, rectangle represents the number of teachers. The eldest ( 50 − 55 years ) = 1 person This is because the height of the rectangle with class interval 50 − 55 as base is 1 unit. The youngest ( 20 − 25 years ) = 2 persons This is because the height of the rectangle with class interval 20 − 25 as base is 2 units.

The following histogram shows the frequency distribution f the ages of 22 teachers in a school: Which age group teachers are more in the school and which least?

The group containing the most number of teachers is 35 − 40 years. This is because the height of the rectangle with class interval 35 − 40 as base is the maximum. The group containing the least number of teachers is 50 − 55 years. This is because the height of the rectangle with class interval 50 − 55 as base is the minimum.
