Show answer and explanation
Correct answer: (D) 8 km, North
Track each leg on a compass grid (a left turn rotates the heading 90° anti-clockwise, a right turn 90° clockwise). Net east-west: East 3 − West 3 = 0 (no east-west shift). Net north-south: North 8 − South 0 = 8 (8 km North). So P is 8 km straight North of A. He is at point P; answer: 8 km, North.
हिंदी में प्रश्न
Suresh बिंदु A से चलना शुरू करता है और पूर्व की ओर 3 किमी चलता है, फिर बाएं मुड़कर 8 किमी चलता है, और अंत में बाएं मुड़कर 3 किमी चलकर बिंदु P पर रुकता है। बिंदु P की बिंदु A से न्यूनतम दूरी कितनी है, और P, A से किस दिशा में है? (सभी मोड़ 90° के हैं।)

सही उत्तर: (D) 8 किमी, उत्तर
प्रत्येक चरण को दिशा-ग्रिड पर लिखें (बाएं मोड़ से दिशा 90° वामावर्त, दाएं मोड़ से 90° दक्षिणावर्त घूमती है)। कुल पूर्व-पश्चिम: पूर्व 3 − पश्चिम 3 = 0 (पूर्व-पश्चिम में कोई विस्थापन नहीं)। कुल उत्तर-दक्षिण: उत्तर 8 − दक्षिण 0 = 8 (8 किमी उत्तर)। अतः P, A से ठीक उत्तर में 8 किमी दूर है। उत्तर: 8 किमी, उत्तर।
