Question

Mala's date of birth is 20-10-1998. What will be her age on 25-06-2021?

• A. 22 years 00 months and 05 days
• B. 21 years 08 months and 05 days
• C. 22 years 07 months and 00 days
• D. 22 years 08 months and 05 days

Answer 1

The correct option is D 22 years 08 months and 05 days

$\begin{array}{c}YYYYMMDD\\ 20210625\\ \underset{–}{-19981020}\\ --05\end{array}$

We make use of the fact that 12 months constitute an year. So, 2021 can be written as 2020 when the 12 months are added off to the 6 months(to give 18 months) as illustrated below:

$\begin{array}{c}YYYYMMDD\\ 20201825\\ \underset{–}{-19981020}\\ 220805\end{array}$

Her age on 25-06-2021 will be 22 years 08 months and 05 days.
