hard Q9 of 15
Step-by-Step Solution
Step 1: Break into yearly spans
From 15 Aug 2018 to 15 Aug 2019 = 365 days (2018→2019 is an ordinary year). From 15 Aug 2019 to 15 Aug 2020 = 366 days (2019→2020 includes Feb 29, 2020 → leap year).Step 2: Add the spans
Total = 365 + 366 = 731 days. This value is the difference in days between the two dates (exclusive of one end).Step 3: Adjust for inclusive endpoints
Because the question asks for the count inclusive of both 15 Aug 2018 and 15 Aug 2020, add 1 → 731 + 1 = 732 days.Final Answer:
732 → Option BQuick Check:
Compute with date difference: (15 Aug 2020 − 15 Aug 2018).days = 731 → plus 1 for inclusive counting = 732 ✅
Quick Trick: Add full-year day counts, then add +1 when both start and end dates are included.
Common Mistakes:
MISTAKES- Adding 365+366 and forgetting to add 1 for inclusive counting (off-by-one error).
