3. [1 mark]
Answer: 323624 (acceptable 323–324 / 624–625 range)
Teaching note: 4-figure base = 3262. Hospital is 3/10 across (easting +3 → 323) and 4/10 up (northing +4 → 624).
4. [1 mark]

5. [1 mark]
Answer: 417732 (or 417 732)
Teaching note: Northernmost temple is in 4173; 7/10 across, 3/10 up → 417 732.
6. [2 marks]
Answer: 2 km
Working:
- Scale 1:50 000 means 1 cm = 50 000 cm = 0.5 km.
- 4 cm × 0.5 km = 2 km.
Marking: 1 mark for conversion, 1 mark for final answer.

9. [1 mark]
Answer: 100 m
Teaching note: X lies on the contour labelled 100 m.
10. [2 marks]
Answer: Wrong because easting/northing reversed or wrong square; correct = 5392.
