1.	The following histogram shows the monthly wages (in Rs) of workers in a factory:(i) In which wage-group the largest numbers of worders are being kept? What is their number?(ii) What wages are the least number of workers getting? What is the number of such workers?(iii) What is the total number of workers?(iv) What is the factory size?
Answer» (i) From the figure, the highest rectangle corresponds to the largest number of workers. The required interval is Rs 950−1000. There are 8 workers in this interval. (ii) The lowest rectangle corresponds to the least number of workers. The required interval is Rs 900−950. There are 2 workers in this interval. (iii) The total number of workers is the sum of workers in all the intervals. It can be calculated as follows: Total workers = 3 + 7 + 5 + 4 + 2 + 8 + 6 + 5 = 40 workers (iv) The factory intervals are 750−800, 800−850, .. 1050−100. Hence, the factory size is 50.
