A photorealistic street math puzzle scene set against an old weathered concrete wall with two wooden stall windows. 

1. Top Banner: A long black signboard displaying a riddle in clean white and yellow text reading "Who is selling at a higher price?".

3. Right Window ("Shop B"): Labeled with a wooden header "Shop B", featuring another vendor behind an identical pile of red onions. A blackboard sign below displays "6 Kilo ₹70".

4. Foreground Customer: A young man standing on the gravel street with his back partially turned, wearing a vertical striped shirt, dark trousers, and white sneakers, looking thoughtfully at the two stalls.

[Customization Rule: The items on the counter (onions, apples, mangoes, or tomatoes), quantities, prices/currency, and top riddle text can be freely changed to compare any produce or product.]

Natural daylighting, realistic street photography, sharp detail, 8k render. [Reference Image Rule: If I upload a photo, preserve my exact facial features, skin tone, eye shape, and facial structure from my uploaded image—replacing either the customer or one of the shopkeepers accordingly. If no photo is uploaded, generate the full scene directly.] --ar 4:5
