Answer
Correct Answer: Thursday
Explanation
Introduction / Context:Another chained-offset problem. We will again introduce an anchor “today = T,” express each phrase in offsets, and then compute the requested weekday carefully.
Given Data / Assumptions:
- T − 2 = Thursday (day before yesterday).
- Tomorrow = T + 1.
- Four days after tomorrow = (T + 1) + 4 = T + 5.
Concept / Approach:From T − 2 = Thursday, find T; then evaluate T + 5. Counting forward on a 7-day cycle gives the result.
Step-by-Step Solution:
1) T − 2 = Thursday ⇒ T = Saturday.2) Four days after tomorrow = T + 5 = Saturday + 5.3) Count forward from Saturday: Sunday (1), Monday (2), Tuesday (3), Wednesday (4), Thursday (5).4) Therefore, the required day is Thursday.Verification / Alternative check:Compute via tomorrow first: Tomorrow is Sunday; four days after that is Thursday—identical outcome.
Why Other Options Are Wrong:
- Monday/Sunday/Wednesday: Each is off by one or more days compared with the T + 5 computation.
- None of these: A correct choice (Thursday) exists.
Common Pitfalls:Forgetting that “day before yesterday” moves two days back, not one; or miscounting the +5 from today rather than +4 from tomorrow. Always reduce to a single offset from T.
Final Answer:Thursday
