Calendar / early vs late arrival: Anil reached a place on Friday and learned he was 3 days earlier than scheduled. If he had reached on the following Sunday instead, how many days late/early would that be relative to the scheduled day?

Introduction / Context:
We compare actual/alternate arrival dates to a fixed scheduled day, counting signed differences.

Given Data / Assumptions:

• Actual arrival: Friday.
• He is 3 days earlier than scheduled.
• Alternate thought: arriving the following Sunday.

Concept / Approach:
If Friday is 3 days early, then Scheduled = Friday + 3 = Monday. Compare Sunday to Monday.

Step-by-Step Solution:

Verification / Alternative check:
Timeline: Fri (actual, -3), Sat (-2), Sun (-1), Mon (0). Hence Sunday is one day before scheduled.

Why Other Options Are Wrong:
They miscount the offset or reverse early/late orientation.

Common Pitfalls:
Counting inclusively instead of true day gaps.

Final Answer:
One day earlier
