Laali is born on 04/07/2014 and Chotu is born on 04/12/2019. Who is older among the two and how much?
Solution:
Since, the year of birth of Laali (2014) is less than the year of the birth of Chotu (2019), so, Laali is older. To find the age difference, we shall find Laali’s age as of 04/12/2019 (Chotu’s birth date).
Year difference: From 04/07/2014 to 04/07/2019 = 5 years
