Answer 1

Hint: -In this question first of all the given age of ashu and his sister in roman numeral is converted into normal number and after that we added both the numbers and found their total age in years. Then we will convert that normal number into roman numeral to get the answer.

Complete step-by-step answer:
Given is:
Age of ashu $=XIX$ years
as we know that roman numeral $XIX$ is $19$
And age of his sister $=XXV$ years
and we know that roman numeral $XXV$ is $25$
Therefore their total age is adding the age of ashu and age of his sister:
$=19+25=44$ years
In roman numeral $44$ is written as $XLIV$.
Therefore the correct option is A.

Note: - Here one should have the knowledge og roman numerals. While converting the roman numerals into normal numbers we have to take care as most of the students commit mistakes in conversion .
