Correct option is D
Given:
1st March of a year is Sunday.
We need to find the day on 1st February of the next year.
Concept & Formula Used:
Count the number of days from 1st March (this year) to 1st February (next year).
Find how many extra days this period has beyond full weeks (use modulo 7).
Add that many days to Sunday to get the answer.
Solution:
Months between March and January (next year):
March – 31
April – 30
May – 31
June – 30
July – 31
August – 31
September – 30
October – 31
November – 30
December – 31
January – 31
Total = 337 days
Now, 337 ÷ 7 = 48 weeks and 1 day
So the day will shift by 1 day from Sunday → Monday
Ans. (d) Monday
