saying 20%alcohol in 15 litre solution.

Ques:- What was the day of the week on 28th February, 1995?
A. Monday
B. Tuesday
C. Wednesday
D. Thursday
Recent Answer : Added by Abhay Chothani On 2022-05-17 08:55:25:
1600 years contain 0 odd day.
300 years contain 1 odd day.
94 years = (23 leap years + 71 ordinary years)
= (46 + 71) odd days
= 117 odd days, i.e., 5 odd days
Days from 1st January 1995 to 28th February 1995
= (31 + 28) days = 59 days
= (8 weeks + 3 days) = 3 odd days
∴ Total number of odd days
= (0 + 1 + 5 + 3) = 9 odd days i.e., 2 odd days.
So, the required day is Tuesday.
