Understanding Direction Sense and Shadows
Direction sense questions involve determining directions based on given information about movement, position, or shadows. This question specifically involves understanding how shadows are cast in the morning.
Sun Position and Shadow Direction in the Morning
In the morning, the sun rises in the East. A shadow is always cast opposite to the direction of the light source. Therefore, in the morning, shadows are cast towards the West.
Analyzing Sanju's Shadow
The question states that Riti sees Sanju coming from a direction, and Sanju's shadow is towards his right. We know that in the morning, Sanju's shadow is cast towards the West.
So, Sanju's right hand side is pointing towards the West.
Determining Sanju's Facing Direction
If Sanju's right is towards the West, we need to determine which direction he is facing. Imagine a person standing such that their right hand is pointing towards the West. Let's consider the main directions:
- If Sanju faces North: His right is East. (Incorrect)
- If Sanju faces South: His right is West. (Correct)
- If Sanju faces East: His right is South. (Incorrect)
- If Sanju faces West: His right is North. (Incorrect)
Therefore, Sanju must be facing South.
Determining Sanju's Direction of Origin
The question asks from which direction Sanju is coming. If Sanju is facing South, he is walking towards the South. If he is walking towards the South, he is coming from the opposite direction, which is North.
So, Sanju is coming from the North.
Step-by-Step Deduction
- Time of day is morning, so the sun is in the East.
- Shadows are cast in the West (opposite to the sun).
- Sanju's shadow is to his right.
- This means Sanju's right side is towards the West.
- If a person's right is West, they are facing South.
- Sanju is facing South.
- If Sanju is facing South, he is coming from the North.
Based on this analysis, Sanju is coming from the North.
Revision Table: Shadow Direction Basics
| Time of Day | Sun Position | General Shadow Direction |

| Morning | East | West |
| Evening | West | East |
| Noon (Exact 12 PM, depending on location) | South (in Northern Hemisphere) | North (in Northern Hemisphere) |
Additional Information: Solving Direction Sense Questions
Here are some tips for solving direction sense questions, especially those involving shadows:
- Always start by determining the direction of the sun based on the time given (morning or evening).
- Remember that shadows are always opposite to the sun's direction.
- Visualize or draw a diagram of the person's orientation. If their shadow is to their left/right/front/back, determine which main direction corresponds to that position relative to the direction of the general shadow.
- Pay close attention to whether the question asks for the direction the person is 'facing', 'walking towards', or 'coming from'. These can lead to different answers. 'Coming from' is the opposite of the direction they are walking towards or facing.
- Consider the hemisphere if noon questions are asked, as the sun's position at noon can be south or north depending on location relative to the equator.
