Question

My date of birth is $ 19 - 11 - 1975 $ i.e. $ 19{\rm{th}} $ November $ 1975 $ . Let us find my age at $ 10 - 10 - 2000 $ .

Answer 1

Hint: This question is based on the calendars. In this question we have to find the age of a person in years, the date of birth is given and the date at which we have to find the age is also given. So, to find the age of the person in years we have to find the difference between the years given.

Complete step-by-step answer:
Given:
The date of birth is $ 19 - 11 - 1975 $ i.e. the day is $ 19{\rm{th}} $ of the month November of year $ 1975 $ .
And, the date at which we have to find the age is $ 10 - 10 - 2000 $ i.e. the day is $ 10{\rm{th}} $ of the month October of the year $ 2000 $ .
Now from the date $ 10 - 10 - 2000 $ it is clear that no birthday happened in the year $ 2000 $ because the birthday happens in the $ 19{\rm{th}} $ of the November month but we are counting only till $ 10{\rm{th}} $ of the October month.
So, the birthday happened from the birth year $ 1975 $ to the year $ 1999 $ .
Now we can find the age by simply finding the difference between the year $ 1999 $ and the year $ 1975 $ .
So, the age of the person is given by –
 $
\Rightarrow {\rm{Age }} = 1999 - 1975\\
 = 24{\rm{ years}}
 $
Therefore, the age of the person is $ 24{\rm{ years}} $ .

Note: It should be noted that we are calculating the age of the person in years so we have to count only those years in which the birthday of the person has happened. For example, in this case we are not counting the year $ 2000 $ because we have to find the age between two specific dates and according to the date $ 10 - 10 - 2000 $ the birthday has not happened in the year $ 2000 $ because the birthday happens in the $ 19{\rm{th}} $ of the November month. So, we will count only the years from $ 1975 $ to $ 1999 $ .
