The number of odd days in a non-leap year is:
- 2
- 4
- 3
- 1
Show answer and solution
Correct answer: D. 1
1. A non-leap year has 365 days.
2. 365 = 52 weeks x 7 + 1, leaving a remainder of 1.
3. So the number of odd days is 1.

7 June 1984 was a Thursday. What day was 7 June 1983?
- Tuesday
- Wednesday
- Sunday
- Monday
Show answer and solution
Correct answer: A. Tuesday
1. From 7 June 1983 to 7 June 1984, the interval includes February 1984, which is a leap year, so the period has 366 days.
2. 366 days = 52 weeks + 2 odd days, so 7 June 1984 is 2 days after 7 June 1983.
3. Thursday − 2 days = Tuesday, so 7 June 1983 was a Tuesday.
