Correct answer: D. 15 km and in West Direction15 किमी और पश्चिम दिशा में
Explanation
10 km north; a left turn from north faces west, so 15 km west; another left turn faces south, 10 km south cancels the 10 km north. Net displacement = 15 km towards the west: 15 km, West.10 किमी उत्तर; उत्तर से बाएँ मुड़ने पर पश्चिम, अतः 15 किमी पश्चिम; फिर बाएँ मुड़ने पर दक्षिण, 10 किमी दक्षिण जाने से 10 किमी उत्तर निरस्त हो जाता है। कुल विस्थापन = 15 किमी पश्चिम: 15 किमी, पश्चिम दिशा।More Logical Reasoning questions
