Which of the following is an informal letter?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A letter to your elder sister congratulating her on her new job
An informal letter is written to family members and friends. A letter to one’s elder sister is personal, so it is informal, whatever its purpose.
Why the Other Options are Incorrect?
Option 1: A letter to the Branch Manager of a bank asking for a new cheque book — Incorrect. A bank manager is an official, so the letter is formal.
Option 2: A letter to the Manager of a hotel thanking the staff for a pleasant family stay — Incorrect. The tone is thankful, but the hotel manager is not a friend or relative. So the letter is formal.
Option 4: A letter to the HR Manager of a company accepting a job offer — Incorrect. It goes to an officer of a company about a job, so it is formal.
