The average monthly salary of 20 workers in an office is ₹ 7650. if the manager’s salary is added, the average salary becomes ₹ 8200 per month. What is the manager’s salary per month?

Answer :

Average monthly salary of 20 workers = 7650 Rs


Total salary of 20 workers per month = 20×7650 = 153000Rs


The wage of one member of the group = 8100 Rs


New average salary of 20 workers and manager = 8200 per month


Let suppose salary of manager is x


The new average (20 workers + manager) = (given)


= 153000 + x = 8200 × 21


153000 + x = 172200


x = 172200 – 153000


x = 19200 Rs


Hence salary of manager is 19200Rs.
