🎯 Business Letter Format Challenge
Identify the errors or missing parts in these letter components.
1. What is wrong with this date format: "03/10/2025" in a business letter?
Reason: 03/10/2025 is ambiguous (could be March 10 or October 3). Business letters use DD Month YYYY format to avoid confusion.
Correct Formats: 10 March 2025 (preferred), March 10, 2025 (also acceptable)
2. When should you use "Yours faithfully" vs "Yours sincerely"?
• Yours faithfully - When you don't know the recipient's name (Dear Sir/Madam)
• Yours sincerely - When you know the recipient's name (Dear Mr. Sharma)
Memory Trick: "Faithfully" for formal/unknown, "Sincerely" for known persons.
Never: "Yours faithfully, Raj" (mismatch) or "Yours truly" (less common now)
3. Which is correct for a complaint letter subject line?
A) Complaint
B) Regarding faulty product
C) Subject: Complaint about defective laptop purchased on 15 Jan
Reason: Subject line must start with "Subject:" and be specific but concise.
Analysis: A) Missing "Subject:" and too vague. B) Missing "Subject:" prefix. C) Perfect - has "Subject:", specific, includes key details.
4. What's wrong with this salutation: "Dear ABC Company Manager,"
Correct Format:
Address: The Manager
ABC Company
[Address]
Salutation: Dear Sir/Madam,
Reason: Salutation is for person, not company. Manager's designation goes in address, not salutation.
5. How many paragraphs should a business letter body have and what should each contain?
Paragraph 1: Introduction - State purpose clearly
Paragraph 2: Details - Provide facts, reasons, evidence
Paragraph 3: Conclusion - State expectation/request action
Example: Complaint letter: 1) State complaint, 2) Describe problem & effects, 3) Request solution
Length: Each paragraph 2-3 sentences, total body 150-200 words for exams
