Answer 1

Hint: Here in this question, we have 6 sub questions. The question is related to the calendar. For every question there is a direct solution. In a year we have 12 months. Some months will have 30 days and some months will have 31 days. In February, once every four years we have 29 days. Otherwise, we have 28 days. If a February month has 29 days, then the year will be considered a leap year. By using this knowledge, we are going to solve the following questions.

Complete step by step solution:
Now we consider the set of questions which are given.
1) How many months are there in a year?
As we know that in a year we have January, February, March, April, May, June, July, August, September, October, November and December.
Therefore there are 12 months in a year.
 2) How many months in a year have 30 days?
In a year totally we have 12 months. April, June, September and November. In these months we have 30 days.
Therefore there are 4 months has 30 days in a year
3) How many months in a year have 31 days?
In a year totally we have 12 months. January, March, May, July, August, October and December. In these months we have 31 days.
Therefore there are 7 months and 31 days in a year.
4) Which month has the least number of days?
The month of February has a few days. Because we have 28 or 29 days in this month.
5) How many days does February have?
If a year is a leap year then the month February has 29 days. If it is not a leap year then February has 28 days.
6) After how many years does a leap year repeat itself?
The leap year will repeat itself every 4 years.

Note: In a year totally we have 365 days and in a leap year we have 366 days. One day will be extra in the leap year when we compare it to the other year. The date 29 in February will come once every four year once. In the February month we don’t have the dates 30 and 31. To remember the number of days in a month the students can take help of the knuckles. One form of the mnemonic is done by counting on the knuckles of one's hand to remember the number of days in each month. Count knuckles as 31 days, depressions between knuckles as 30
