BTuesday
CWednesday

Answer:
A. Thursday
Read Explanation:
Solution:
We’ll divide 2013 in different years
2000 years + 12 years + 2013 ( Jan + Feb + March + April + May + June + July + till 15 august)
There are 3 leap years and 9 non-leap years from 2001 to 2012. Therefore, no. of odd days in this period = 1
Also, 2013 is a non-leap year.
Thus, odd days in the given above years = [0 + 1 + (3 + 0 + 3 + 2 + 3 + 2 + 3 + 1)] mod 7
Total odd days = 18 and 18 ÷ 7 = 4 (remainder)
Days codes:
Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
0 | 1 | 2 | 3 | 4 | 5 | 6 |
Code 4 is for Thursday.
Hence, “Thursday” is the correct answer.
