Final answer:
To find the year when the father's age will be double the son's age, determine the number of years needed for the father's age to double that of the son's age and add it to 1991, resulting in the year 2014.
Explanation:
To solve this problem, we need to set up an equation. Let 'x' represent the number of years from 1991 to the year when the father's age will be double the son's age. In 1991, the father's age was 50 (1941 birth year), and his son was 27. So, the equation would be: 50 + x = 2(27 + x). Solving this equation gives x = 23, which means the year will be 1991 + 23 = 2014.
