1. Let there be x, y, and z employees working in departments X, Y, and Z, respectively.
2. x = \(20\% * 75 = 15\).
3. x + y + z = 75. We also know that z - y = 10 or z = y + 10.
4. This means that \(x + y + z = 75 \rightarrow 15 + y + y + 10 = 75 \rightarrow 2y = 50 \rightarrow y = 25\). Then z = 35.
5. Our answer will be: Department Y - 25 and Department Z - 35.
