GATE Mechanical 2021 Set 2 | GA | Question: 5

Question

The front door of $\text{Mr. X's}$ house faces East. $\text{Mr. X}$ leaves the house, walking $\text{50 m}$ straight from the back door that is situated directly opposite to the front door. He then turns to his right, walks for another $\text{50 m}$ and stops. The direction of the point $\text{Mr. X}$ is now located at with respect to the starting point is ____

• A. South-East
• B. North-East
• C. West
• D. North-West

Answer 1

The front door of Mr. X's house faces East. Then the back door of Mr. X's house faces West (the back door that is situated directly opposite to the front door).

$\therefore$ The direction of the point $\text{Mr. X}$ is now located at with respect to the starting point is North-West.

So, the correct answer is $(D).$

Comments

One important point :- If the question had asked about direction with repect to final point then answer would have been south east.

---

what if i assume the direction differently i mean what if i assumed straight from the back door is south then the answer would be south east na how to approach these type of questions?

---

In the question it is clearly mentioned that the back door is situated directly opposite to the front door, and as the front door is facing East, how can u assume that the back door is in south?

Just draw a rough sketch for this type of question to simulate the event mentioned.

understood.

Answer 2

The front door of Mr. X's house faces East. Then the back door of Mr. X's house faces West (the back door that is situated directly opposite to the front door).

$\therefore$ The direction of the point $\text{Mr. X}$ is now located at with respect to the starting point is North-West.

So, the correct answer is $(D).$

Answer 3

Since it faces EAST, therefore the opposite will be WEST, turning right facing west means now going towards North. And since we have to compare the current position's direction in comparison with the initial point. We'll get the answer as North West. Therefore the correct option is:

D. NORTH WEST.
