Question

Which year subsequent to $1990$ had the same calendar as that of the year $1990$ ?

• A. $1998$
• B. $2002$
• C. $1996$
• D. $2001$
• E. $1995$

Answer 1

Answer: (D)

$2001$

Count the number of odd days from the year 1990 (an ordinary year) onwards to get the sum equal to 0 odd day.

Year	1990	1991	1992	1993	1994	1995	1996	1997	1998	1999	2000
Odd day	1	1	2	1	1	1	2	1	1	1	2

Sum of days = 1 + 1 + 2 + 1 + 1 + 1 + 2 + 1 + 1 + 1 + 2 = 14 days = 2 weeks or 0 odd days
Therefore, calendar for the year 1990 will be the same as that of 2001 (The year 1996 is neglected as 1990 is an ordinary year and 1996 is a leap year).
Hence, option (D) is the correct answer.
