1. What will be the day of the week on 14 September 3041 ? [SSC Stenographer 10/12/2024 (Morning)]

Correct Answer: (b) Tuesday
Solution:Formula for calculating day of any date 0 = sunday, 1 = monday.... 6 = saturday A = century code (4,2,0,6 for remainder 1,2,3,0) where remainder = dividing by first two digit of the year by 4 B = last two digits of year C = number of leap years fallen in that century before that date. D = month code (respective code of the months are 0, 3, 3, 6, 1, 4, 6, 2, 5, 0, 3, 5) E = date Day = remainder of (A + B + C + D + E) when divided by 7. For 14 September 3041, A = 2 B = 41 C = 10 D = 5 E = 14 According to formula, Remainder of (A + B + C + D + E)/7 = 72/7 is 2 ⇒ Hence, 2 stands for Tuesday.

2. If the year is NOT a leap year, then how is the last day of the year and first day of the same year related? [SSC CHSL 01/07/2024 (1st Shift)]

Correct Answer: (d) They are the same.
Solution:They are the same 365 (days total) - 1 day (the first day) = 364 days remaining. Total weeks = 364 days ÷ 7 days/week = 52 weeks + 0 days remaining Since there are no extra days beyond the complete weeks, the last day of the year will be the same day of the week as the first day. Therefore, if the first day of the year is a Monday, the last day of that year will also be a Monday

3. If exactly 1 year and 2 days later it is Tuesday, then what day is it today? It is not a leap year. [SSC CGL 18/07/2023 (3rd shift)]

Given year is 2009 , whose previous year is 2008 and 2008 is a leap year so as per condition we add 6 into 2009 then we get, ⇒ 2009 + 6 = 2015
