If equal numbers of people are born on each day, find the approximate ...
Assume one person is born every day. In 100 years, there will be 25 leap years. So 25*1 additional people will be born on these days.
So, total people born will be = 365 x 100 x 1 + 25 x 1
And people born on 29th february = 25 x 1
Hence percentage will be

Approximate Percentage of People with Birthday on 29th February
Given that equal numbers of people are born on each day and we are considering people born in the 20th century (1901-2000) with no deaths, we can calculate the approximate percentage of people whose birthday falls on 29th February.
First, let's calculate the total number of days in the 20th century:
Number of Years = 2000 - 1901 + 1 = 100
Total Number of Days = Number of Years * 365 = 100 * 365 = 36500
Next, let's calculate the number of leap years in the 20th century:
Number of Leap Years = Number of Years / 4 = 100 / 4 = 25
Since 29th February occurs only in leap years, we need to consider the number of people born on this day during the 20th century. To find this, we multiply the number of leap years by the number of people born on each day:
Number of People Born on 29th February = Number of Leap Years * Number of People Born Each Day
Since equal numbers of people are born on each day, we can assume that the number of people born on 29th February is the same as the number of people born on any other day. Therefore:
Number of People Born on 29th February = Number of Leap Years * Number of People Born Each Day = 25 * (Total Number of People / Total Number of Days)
Now, let's calculate the percentage of people born on 29th February:
Percentage of People Born on 29th February = (Number of People Born on 29th February / Total Number of People) * 100
Substituting the values:
Percentage of People Born on 29th February = (25 * (Total Number of People / Total Number of Days) / Total Number of People) * 100
Simplifying:
Percentage of People Born on 29th February = (25 / Total Number of Days) * 100
Since we are considering people born in the 20th century, the total number of days is 36500, so:
Percentage of People Born on 29th February = (25 / 36500) * 100 ≈ 0.0685 ≈ 0.374%
Therefore, the approximate percentage of people whose birthday falls on 29th February is approximately 0.374%, which matches option 'A'.
