**Given data:**
- Thickness of damp proof course (DPC) = 25 mm
- Proportion of cement mortar = 1:6
- Length of room = 5 m
- Width of room = 4 m
- Thickness of wall = 0.3 m

**Calculation:**

1. **Area of the room:**
- Area of the room = Length × Width
- Area of the room = 5 m × 4 m
- Area of the room = 20 m²

2. **Volume of the wall:**
- Volume of the wall = Area of the room × Thickness of the wall
- Volume of the wall = 20 m² × 0.3 m
- Volume of the wall = 6 m³

3. **Volume of DPC:**
- Volume of DPC = Area of the room × Thickness of DPC
- Volume of DPC = 20 m² × 25 mm
- Volume of DPC = 0.02 m² × 0.025 m
- Volume of DPC = 0.0005 m³

4. **Volume of cement mortar:**
- Volume of cement mortar = Volume of the wall - Volume of DPC
- Volume of cement mortar = 6 m³ - 0.0005 m³
- Volume of cement mortar = 5.9995 m³

5. **Quantity of cement and sand:**
- Proportion of cement mortar = 1:6
- Total proportion = 1 + 6 = 7
- Quantity of cement = (1/7) × Volume of cement mortar
- Quantity of cement = (1/7) × 5.9995 m³ = 0.8571 m³
- Quantity of sand = (6/7) × Volume of cement mortar
- Quantity of sand = (6/7) × 5.9995 m³ = 5.1429 m³

6. **Unit of quantity:**
- The unit of quantity for cement and sand is cubic meters (m³) as per the calculations above.

**Answer:**
The unit of quantity of damp proof course (DPC) of 25 mm thick in cement mortar 1:6 for a room of size 5 m length and 4 m width is 0.8571 m³ of cement and 5.1429 m³ of sand.
