Rahul is facing south-east. He turns 90° in the clockwise direction and then 135° in the anticlockwise direction. Which direction is he facing now?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → East
The eight directions are 45° apart, so a turn of 90° moves two directions round the compass and a turn of 135° moves three. Each turn starts from the direction he is facing at that moment:
Facing South-East, 90° clockwise (South-East → South → South-West): he faces South-West
Facing South-West, 135° anticlockwise (South-West → South → South-East → East): he faces East
Shortcut: The net turn is \(135-90=45\)° anticlockwise, and 45° anticlockwise from South-East is East.
