The arrow on a signboard points towards the North-East. The board is turned so that the arrow rotates through \(135^\circ\) in the clockwise direction. In which direction does the arrow point now?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → South
On the compass the eight directions are \(45^\circ\) apart; clockwise they run North → North-East → East → South-East → South → South-West → West → North-West.
\(135^\circ=3\times45^\circ\), so the arrow moves 3 steps clockwise
From North-East: 1 step to East, 2 steps to South-East, 3 steps to South
The arrow now points South.
