Answer:
The first day of the Year or Month January is Monday.
Step-by-step explanation:
Given:
January has exactly 4 Thursday and 4 Sundays.
To find: First day of the Year or Month January.
We know that there are exactly 4 weeks in a month of 30 days.
We also knows that there are 7 days in a week.
Number of days in 4 week = 4 × 7 = 28 days
Number of days in Month January = 31
So, we left with 31 - 28 = 3 days.
If month starts with Monday then after 4 week we have Monday , Tuesday , Wednesday for last 3 days which also has exact 4 Thursday and 4 Sundays.
If month starts with Tuesday then after 4 week we have Tuesday , Wednesday , Thursday for last 3 days which has 5 Thursday and exact 4 Sunday.
Similarly for any other day we don't have exactly 4 Thursday and 4 Sundays.
Therefore, The first day of the Year or Month January is Monday.
