Transformation into Indirect Imperative Sentence
To change the statement "Ramu Seth was calling me" into an indirect imperative sentence, we need to follow certain rules of transforming direct speech into reported speech.

Steps to Convert the Statement
- Start the sentence with a reporting verb like 'requested', 'asked', or 'told'.
- Use the word 'to' before the verb in the reported speech.
- Change the verb form to the base form.
- Include the object pronoun 'me' in the reported speech.

Transformation Process
1. Begin the sentence with a reporting verb:
- Ramu Seth requested me to change.
2. Add the word 'to' before the verb:
- Ramu Seth requested me to change into an indirect imperative sentence.
3. Change the verb form to the base form:
- Ramu Seth requested me to change into an indirect imperative sentence.
4. Include the object pronoun 'me':
- Ramu Seth requested me to change it into an indirect imperative sentence.
Therefore, the transformed indirect imperative sentence would be: "Ramu Seth requested me to change it into an indirect imperative sentence." This sentence conveys the same meaning as the original statement but in a more indirect and polite manner.
