Question

During a long-distance sea voyage, without the Captain realising, steering of the ship started malfunctioning in the following manner. When the Captain was trying to turn the ship 60 degrees to the left, ship was turning 30 degrees to the right. When the Captain was trying to turn the ship 90 degrees to the left, ship was turning 90 degrees to the right. When the Captain was trying to turn the ship 45 degrees to the right, ship
was turning 30 degrees to the left. When the Captain was trying to turn the ship 90 degrees to the right, ship was turning 45 degrees to the left.
Before the malfunction, ship was going in North-East direction. After the malfunction started, without realising the problem, the Captain tried to turn 90 degrees to the left, then 90 degrees to the right, then 45 degrees to the right and finally 60 degrees to the left. Find the current direction of the ship.

• A. NORTH EAST
• B. EAST
• C. WEST
• D. NORTH WEST

Answer 1

The Correct Option is B

To determine the current direction of the ship, we need to interpret the operations applied by the Captain under the malfunction conditions. The initial direction is North-East. 

• Initial Position: North-East.
• First Turn: Captain tries 90° left; Ship turns 90° right.
  • From North-East, a 90° right turn results in facing South-East.
• Second Turn: Captain tries 90° right; Ship turns 45° left.
  • From South-East, a 45° left turn results in facing East.
• Third Turn: Captain tries 45° right; Ship turns 30° left.
  • From East, a 30° left turn results in facing North-East.
• Fourth Turn: Captain tries 60° left; Ship turns 30° right.
  • From North-East, a 30° right turn results in facing East.

Thus, the current direction of the ship is EAST.
