    Solution

    At the time of their marriage, the ratio between the ages of Reena and Rahul was 9:10 respectively. Let’s assume the ratio between the ages of Reena and Rahul, at the time of their marriage was ‘9a‘ and ‘10a‘ respectively. After ‘y’ years of their marriage, a daughter will be born. The sum of the ages of the couple and her daughter after (y+2) years of their marriage will be 98 years. 9a+(y+2)+10a+(y+2)+2 = 98 Here two variables are available in the single equation and we don’t have any additional information to form more equations. So the answer cannot be determined from the given information in the question.
