Your question is Footfall Estimation for a Pharmacy. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
They asked you to find the footfall in a pharmacy in your area; how would you estimate it? Explain how you would define footfall, select an observation period, build the estimate from available evidence, and validate the result. State your assumptions clearly and distinguish between a quick estimate and a reliable measurement plan.
