In the year 1910, which of the following month had 5 Thursdays?
I. March
II. May
Show answer & explanation
Correct answer: A
Explanation
The year 1910 was a common year (not a leap year).
According to the calendar, March 1, 1910, was a Tuesday.
If March 1st was a Tuesday:
March 2 = Wednesday
March 3 = Thursday
Since March has 31 days, the days of the week that fall on the 1st, 2nd, and 3rd of the month occur 5 times during the month.
Therefore, in March 1910, Thursday fell on the 3rd, 10th, 17th, 24th, and 31st. (A total of 5 Thursdays)
May 1910:
Since March has 31 days, April 1, 1910, was a Friday.
April has 30 days; therefore, May 1, 1910, was a Sunday.
If May 1st was a Sunday, then Thursday fell on the following dates:
May 5 = Thursday
May 12, 19, and 26 were also Thursdays.
Thus, there were only 4 Thursdays in May 1910.
Conclusion:
Only March 1910 had 5 Thursdays.
The correct option is only I.
