Answer 1

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
