If the following data, the no. of workers getting
wages less than 30 are
:
Wages Rs. 10-20/20-30/30-40/40-50

No. of workers. 6/12/18/24​

Answer 1

The answer is 18 workers .

This because due to following reasons

• the given data is in the exclusive form of grouped data
• so we take no. of workers from the only first two data of wages
• in first 10 to 20 the workers is 6 and in second 20 to 30 the workers is 12
• now we add the first and second workers
• then we get 6 plus 12 is equal to 18
