If 15th January, 2020 was a Wednesday, then what day of the week was it on 31st December of that year?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Thursday
-
Given: 15th January 2020 = Wednesday
-
Find: Day on 31st December 2020
-
2020 is a leap year
Let’s count the number of days from 15 Jan to 31 Dec 2020.
We know:
-
Total days in a year = 366 (leap year)
-
Days till 15 Jan = 15
-
So, days from 15 Jan to 31 Dec = 366 − 15 = 351
Now, let's find the number of odd days by dividing the total number of days by 7: 351 ÷ 7 = 50 weeks with a remainder of 1.
So the day advances by 1 days from Wednesday: Wednesday + 1 day = Thursday
