If every vowel is replaced by its previous vowel for example E is replaced by A and A is replaced by U, then how can AUTO be written as?

To solve the problem of replacing each vowel in the word "AUTO" with its previous vowel, we first identify the vowels and their replacements based on the given rules.

1. Break Down the Problem

• Identify the vowels in the word "AUTO":
  • A
  • U
  • O
• Replace each vowel with its previous vowel based on the provided mapping.

2. Relevant Concepts

• The vowels are ordered as follows:
  • A → U (previous vowel for A is U)
  • E → A
  • I → E
  • O → I
  • U → O

3. Analysis and Detail

• Replace each vowel in "AUTO":
  • A → U (Replaces A)
  • U → O (Replaces U)
  • O → I (Replaces O)

4. Verify and Summarize

• After replacing, we get:
  • A (becomes U)
  • U (becomes O)
  • O (becomes I)

Thus, the word "AUTO" is transformed as follows:

• A → U
• U → O
• O → I

Final Answer

Therefore, "AUTO" is written as "UOI".
