Use the number provided for the case unless there is a clear reason to clarify what it represents.
Case interviews often use simplified or fictional figures so the math stays manageable.
If you believe the interviewer said 30 million but the country actually has 50 million people, confirm, 'We'll use 30 million for this estimate, correct?' and continue.
Clarify the number once if needed, then treat the confirmed figure as a case assumption.
