In a factory, the average salary of the employees is Rs 7000. If there are 12 officers whose average salary is Rs 40000 and the average salary of the remaining employees is Rs 6000, then the total number of employees is:
A402
B404
C406
D408 ✓ Correct
Correct answer: (D) 408 — The total number of employees is 408, so that is the answer.
Explanation
★The total number of employees is 408, so that is the answer.
★Let the total number of employees be x, with average salary 7000.
★The 12 officers earn 12 times 40000, and the remaining x minus 12 earn 6000 each.
★So 7000x equals 12 times 40000 plus (x minus 12) times 6000.
★This simplifies to 1000x equals 12 times 34000, that is 408000.
★Dividing gives x equals 408 employees.
