Correct AnswerExplanation:
- Let's break down Anand's bus journey.
- The bus starts from Anand’s house and takes a right turn, travels 3 km.
- Then, it takes a left turn and travels 2 km.
- Finally, another right turn and covers 4 km, arriving at school.
- At school, the bus faces southeast.
Let's find the initial direction:
- Let’s assume the initial direction is X.
- First right: now facing X + 90°
- Then left: now facing X + 90° - 90° = X (again)
- Then right: now facing X + 90°
So, after these turns, facing X + 90°, the direction is southeast.
What is X? It must be northeast, since northeast + 90° = southeast.
