C. 560000 लोग560000 people
Simple Explanation
कुल population \(875\times640\) होगी। \(875\times64=56000\) इसलिए \(875\times640=560000\) लोग। विकल्प C सही है। unit analysis से persons per square kilometre multiplied by square kilometres gives persons। परीक्षा में multiplication को smaller factors में तोड़कर solve करना arithmetic errors कम करता है। / Total population is \(875\times640\). Since \(875\times64=56000\), multiplying by 640 gives 560000 people. Therefore option C is correct. Unit analysis confirms the operation because persons per square kilometre multiplied by square kilometres gives persons. Breaking the multiplication into smaller factors reduces arithmetic errors.
