Solution

Frequency distribution of the given weekly wages of 15 workers:

(i) Minimum wage = Rs. 150
Maximum wage = Rs. 350
∴ Range = Maximum wage − Minimum wage
= Rs. 350 − Rs. 150
= Rs. 200
(ii) Numbers of workers getting Rs. 350 = 1 worker

(iii) Here, minimum wage Rs. 150
Number of workers getting Rs. 150 = 3 workers
∴ Number of workers getting minimum wages = 3 workers
