Answer 1

Answer:

Number of officers is 75.

Step-by-step explanation:

Total staff=600

Average salary of all staff= 19750

Therefore, total salary = 19750*600 = Rs. 11850000

Let the number of officers be x

So, number of other staff= 600-x

Salary of officer= Rs.32000

Salary of other staff= Rs.18000

Therefore, we can write:

32000x +18000(600-x) = 11850000

On solving, we get x= 75

Hence, number of officers= 75.
