1. How old is Bincy by 02/05/2005?

Ans: Steps to find how old Bincy is,

  • From the Birth Certificate we know that Bincy was born on 02/05/2002. 

  • As per the question we have to find how old Bincy is, which means we have to find her age. 

  • Then we can minus the current date to the date of birth.

  • Then it will be, 02/05/2005 - 02/05/2002

  • The date and month of birth are the same on both of the dates. Hence we can minus the year 2005 - 2002 = 3

  • Hence Bincy will be 3 years old.


2. Bincy was born on 02 ……….. 2002.

Ans: As per the Birth Certificate, Bincy was born on 02/05/2002.


3. On which date this birth certificate was registered?

Ans: It is mentioned in the Birth Certificate that it was registered on 02/05/2002.

4. By 02/05/2010, Bincy will be eight years old. True / False.

Ans: By following the same steps mentioned above, we will calculate the age of Bincy by 02/05/2010.

So we will minus 02/05/2010 by 02/05/2002.

Since both dates and months are the same, we can minus the year.

So, 2010 - 2002 = 8

Hence the given statement is true.
