Indirect Interrogative and Ramu's Statement
Ramu indirectly interrogated by asking "Who was calling me?" This type of sentence is known as an indirect interrogative. In an indirect interrogative sentence, a question is embedded within a statement or another type of sentence structure.

Ramu's Intent
Ramu's intention behind asking this indirect interrogative could be to inquire about the identity of the person who was calling him. By framing the question in this way, he may have been seeking information without directly asking a straightforward question.

Interpreting Indirect Interrogatives
Indirect interrogatives are often used to sound more polite or subtle in communication. They can also be used to express curiosity or seek clarification without appearing too direct. In this case, Ramu's indirect interrogative suggests a level of interest in knowing who was trying to reach him.

Responding to Indirect Interrogatives
When someone uses an indirect interrogative, it is important to pay attention to the context and tone of the conversation. By understanding the underlying question, you can provide a relevant and informative response. In this scenario, you could answer by stating the name or identity of the person who was trying to contact Ramu.

Conclusion
Indirect interrogatives add a layer of complexity to communication by embedding questions within statements. By recognizing and interpreting these structures, you can effectively respond and engage in meaningful dialogue with others.
