Direction sense MCQ — 9 Practice Questions with Answers

Explanation

Start from East. A clockwise turn of 135° takes the person past South-East and South to South-West, because each diagonal step is 45°. From South-West, a 180° anticlockwise turn points exactly to the opposite direction, which is North-East. West would require a different final angle, South is reached midway during the first turn, and South-East is only the first 45° stage from East. The final facing direction is therefore North-East.

Explanation

Take A as the reference point. B is placed to the east of A, while D is placed to the north of A. Now judge D’s position from B, not from A. From B, one has to move left towards A and then upward towards D. That direction is north-west. Pure west would stop at A’s horizontal line, and pure north would require D to be directly above B. South is the opposite vertical direction, so it cannot fit the arrangement.

Explanation

Take the office as the starting point. Ajay goes 5 km east and, after turning left, 12 km north, so his home is at coordinates (5, 12). Rakesh goes 5 km west and, after turning left from west, 12 km south, so his home is at (-5, -12). The straight-line distance between the homes is based on horizontal separation 10 km and vertical separation 24 km: √(10² + 24²) = √676 = 26 km. The other distances do not match this right-triangle calculation.

Explanation

The change is a fixed rotation of directions. South-East becoming North means every direction has moved three steps anticlockwise on the eight-direction compass. The second clue confirms this: North-East also moves three anticlockwise steps to become West. Applying the same rotation to South, move three steps anticlockwise: South to South-East, then East, then North-East. Therefore South becomes North-East. North-West, South-West and North do not match this same three-step rotation.

Explanation

The direction change is a fixed rotation. North-East becoming West means every direction is shifted by 135 degrees anticlockwise. The second condition confirms this: South-East shifted by 135 degrees anticlockwise becomes North. Applying the same shift to East gives North-West. South-East would result from a different movement, while North and South do not fit the rotation already established by the two examples. Therefore, East changes to North-West under this direction code.
