A small media company got 20 employees.

The employee consists of reporters, camera-man and the writers

Every reporter earns daily $3, camera-man 1.5$ and writers earn 0.5$

How many reporters, camera-man and the writers are there?

reporters=2, camera-man=5 and the writers=13

Let the number of reporters, camera-man, and writers are denoted by r, c, and m respectively.

From the given information we can write the following 2 equations;

r + c + m = 20 . . . . . . (1)

3r + 1.5c + 0.5m = 20 . . . . . (2)

Multiplying equation (2) by 2 we get;

6r + 3c + m = 40 . . . . . (2)

equation3 - equation 1

5r + 2c = 20

The unique solution with whole numbers is r = 2 & c = 5

Therefore from equation(1) we can find;

m = 13

=> reporters=2, camera-man=5 and the writers=13
