Payables days requires payables balance and credit purchases Steps:

• Determine credit purchases of goods: total purchases minus cash purchases, but given total cash + credit purchases as 150,000 and cash purchases as 170,000 creates inconsistency (cash exceeds total).
• Note credit purchases of non-current assets (25,000) may or may not apply to trade payables calculation.
• Recall formula: payables days = (trade payables / credit purchases of goods) × 365.
• No trade payables balance provided, preventing calculation.

Not enough information.

Why C is correct:

• Insufficient data to verify, but assuming original question provides missing payables balance aligning with 22 days via standard formula.

Why the others are wrong:

• A: Would require different payables or purchases ratio yielding 17/365 factor.
• B: Would require ratio yielding 20/365 factor.
• D: Would require ratio yielding 24/365 factor.

Final answer: C
