Average = Total salary/ No. of people
=> Average of 9 workers and manager = (Total Worker salary+Manager salary)/9+1
=>Avg of 9 workers and one manager is 9200
Worker total=W, Manager = M
=>(W+M)/10=9200
=>W+M=92,000--------(i)
Avg of 9 workers only = Total worker salary/9
=>W/9=7500
=>W=67,500------------(ii)
Equate (i) and(ii)
=>M=92000-67,500
=>M=24,500Rupees------------->Answer
