Difficulty: Medium
Correct Answer: Friday
Explanation:
Introduction / Context:We find the weekday shift from 25 June to 15 August in the same year.
Given Data / Assumptions:25 June = Wednesday; July has 31 days; June has 30 days; August target date is the 15th.
Concept / Approach:Compute day offset: June 25 → August 15 equals 51 days (5 days to June 30, 31 days of July, and 15 days of August minus 0 because we start counting from June 25 to Aug 15 exclusive of the start day).
Step-by-Step Solution:
Total offset = 51; 51 mod 7 = 2.Wednesday + 2 = Friday.Verification / Alternative check:Break the path: 25 Jun → 25 Jul = 30 days (≡ 2), then +21 days to 15 Aug (≡ 0), net ≡ 2.
Final Answer:Friday
