Correct answer: D. North-Eastउत्तर-पूर्व
Explanation
Measure directions clockwise from North: East = 90°. Turning 100° clockwise gives 190°. Turning 145° anti-clockwise gives 190° − 145° = 45°, which is North-East. (Net turn = 45° anti-clockwise from East.)दिशाओं को उत्तर से घड़ी की दिशा में मापें: पूर्व = 90°। 100° दक्षिणावर्त घूमने पर 190°। फिर 145° वामावर्त घूमने पर 190° − 145° = 45°, जो उत्तर-पूर्व है। (कुल घुमाव पूर्व से 45° वामावर्त।)More Reasoning & Mental Ability questions
