In the year 1924, which of the following month had 5 Thursdays?
I. March
II. May
Show answer & explanation
Correct answer: B
Explanation
1924 is a leap year (divisible by 4).
February = 29 days.
The day of January 1, 1924:
January 1, 1900 = Monday.
Let's calculate the odd days up to 1924:
1901–1923 = 23 years.
Ordinary years = 17 → 17 odd days.
Leap years = 6 → 6 × 2 = 12 odd days.
Total = 17 + 12 = 29.
29 / 7 = 1 (Remainder).
January 1, 1924 = Monday + 1 = Tuesday.
3: March 1924
January (31 → +3), February (29 → +1).
March 1 = Tuesday + 3 + 1 = Saturday.
March = 31 days → 4 weeks + 3 days.
Extra days = Saturday, Sunday, Monday.
Thursday will not occur 5 times.
March (31 → +3), April (30 → +2).
May 1 = Saturday + 3 + 2 = Thursday.
May = 31 days → 4 weeks + 3 days.
Extra days = Thursday, Friday, Saturday.
Thursday occurs 5 times.
Correct Answer = Only II (May).
