Question : A man is born in the year 1896 A.D. If in the year $x^2$ A.D. His age is $(x-4)$, the value of $x$ is:
Option 1: 40
Option 2: 44
Option 3: 36
Option 4: 42
Correct Answer: 44
Solution : Let the man's age be $x$. According to the question, $x^2 - 1896 = x - 4$ or, $x^2 - 1896 - x + 4 = 0$ or, $x^2 - x - 1892 = 0$ or, $x^2 - 44x + 43x - 1892 = 0$ or, $x$ = 44, – 43 Since age can not be negative, so, $x = 44$ Hence, the correct answer is 44.
