The average monthly salary of employees, consisting of officers and workers, of an organisation is Rs. 3000. The average salary of an officer is Rs. 10,000 while that of a worker is Rs. 2000 per month. If there are total 400 employees in the organisation, find the number of officers and workers separately.

250, 150
310, 90

Validate

Solution:

\text"Number of officers"/\text"Number of workers" = 1000/7000 = 1/7

No. of officers =

1/{1+ 7} × 400

= 50
No. of workers = 400 – 50 = 350
