#8# workers

Explanation:

Total number of workers inclusive of all categories = #5+3+1# = #9#

Payment to category "C" workers = #Rs. 20,000xx5# =# Rs. 100,000#

Payment to "B" category workers = #Rs. 25,000xx3# = #Rs. 75,000#

Payment to "A" category worker = #Rs. 65,000xx1#=#Rs. 65,000#

Therefore, total payment made by the company to all category of workers = #100,000+75,000+65,000# =# Rs. 2,40,000#

Now, mean salary of workers = (Total salary) /(number of workers)

Which would be = #240000/9# = #Rs. 26,666.66#

So, all workers getting below #Rs. 26,666.66# are earning less than the mean salary which in other words are all category "C" and category "B" workers

Number of category "C" and category "B" workers = #5+3# = #8#
