What was the day of the week on 2nd January 2010, if it was Sunday on 1st January 2006?

Saturday

The correct answer is Option (1) → Saturday

Given:
1st January 2006 was a Sunday

We need the day on 2nd January 2010.

Step 1: Count odd days from 2006 to 2009

Total odd days = 1 + 1 + 2 + 1 = 5

Step 2: From 1 Jan 2010 to 2 Jan 2010

1 additional day → 1 odd day

Total odd days = 5 + 1 = 6

Step 3: Find the day

Sunday + 6 days = Saturday
