• A. Sunday
• B. Tuesday
• C. Monday
• D. Wednesday

Answer 1

The Correct Option is C

To ascertain the day of the week for 16th March 2020, given that 26th January 2020 was a Sunday, the procedure involves calculating the interval between these dates and determining the resultant day. The following outlines the process:

1. Determine the number of days within each relevant month:
   • January: 31 days
   • February: 29 days (as 2020 is a leap year)
   • March: 16 days
2. Calculate the total number of days from 26th January to 16th March. Days remaining in January after the 26th are: 31 - 26 = 5 days.
3. Sum the days from January, February, and March: 5 (January) + 29 (February) + 16 (March) = 50 days.
4. Identify the day of the week for 16th March by advancing 50 days from Sunday: 50 mod 7 = 1.
5. A remainder of 1 indicates that 16th March 2020 falls one day after Sunday. Consequently, 16th March 2020 is a Monday.
