(3) She was born in the year 2008. Her age in 2052 will be 44 years (2052 − 2008 = 44) So, Bincy will be 44 years old in 2052.

-2002 = 12 years She is 12 years old in the year 2014.

(7) Bincy was born on 2 May, 2002 and the birth certificate was issued on 5 August, 2002. Now, May is the 5th month of the year and August is the 8th month of the year. So, the number of months after her birth when her certificate was issued = (8
