Problem Analysis:
- The man is initially facing North-West.
- He turns 180° in an anticlockwise direction and walks 140 m.
- He then turns 135° in a clockwise direction and walks 120 m.
- We need to determine the final direction the man is facing.
Solution:
Let's break down the problem step by step:
Step 1: Initial Direction
The man is initially facing North-West.
Step 2: First Turn
The man turns 180° in an anticlockwise direction. This means he turns around completely and now faces the opposite direction. Since he was facing North-West, he now faces South-East.
Step 3: First Walk
The man walks 140 m in the direction he is now facing, which is South-East. This step does not affect his direction.
Step 4: Second Turn
The man turns 135° in a clockwise direction. This means he rotates towards the right. Since he was facing South-East, he now faces South.
Step 5: Second Walk
The man walks 120 m in the direction he is now facing, which is South. This step does not affect his direction.
Step 6: Final Direction
After the second walk, the man is facing South.
Conclusion:
After turning 180° anticlockwise, walking 140 m, turning 135° clockwise, and walking 120 m, the man is facing South. Therefore, the correct answer is option 'C' - South.
