JAMIA | Reasoning | 2022
I am facing south, I turn right and walk 20m. Then I turn right again and walk 10 m. Then I turn left and walk 10 m and then turning right walk 20 m. Then I turn right again and walk 60 m. In which direction am I from the starting point?
Choose the correct answer:
A.
North
B.
North-west
(Correct Answer)
C.
East
D.
North east
Correct Answer:
North-west
Explanation
Movement Analysis
Initial Position:(0,0), facing South.
Step 1: Turn Right (now facing West) and walk 20 m.
New Position=(0−20,0)=(−20,0)
Step 2: Turn Right (now facing North) and walk 10 m.
New Position=(−20,0+10)=(−20,10)
Step 3: Turn Left (now facing West) and walk 10 m.
New Position=(−20−10,10)=(−30,10)
Step 4: Turn Right (now facing North) and walk 20 m.
New Position=(−30,10+20)=(−30,30)
Step 5: Turn Right (now facing East) and walk 60 m.
New Position=(−30+60,30)=(30,30)
2. Final Direction Analysis
The final coordinates are (30,30).
The x-coordinate is positive (+30), indicating the East direction.
The y-coordinate is positive (+30), indicating the North direction.
The point (30,30) lies in the quadrant between North and East.
Final Answer
Direction=North-East
