The average salary per head of all the workers in a company is 95. The average salary of 15 officers is 525 and the average salary per head of the workers is 85. Find the total number of workers in the workshop.
Assume officers are not part of workers .
No of Rest workers = Total man power - [ Workers + Officers ]
W1 means salary of person 1 and so on...
Avg salary of n workers per head
( W1 + ......+ Wn ) / n = 95 ----(i)
Avg salary of 15 officers per head
( O1 + ...... + O 15 ) / 15 = 525 ----(ii)
Avg salary of rest workers per head
( r 1 + ...... + rTotal man power - [ Workers + Officers ] ) / ( Total man power - [ Workers + Officers ] ) = 85 ----(iii)
