What will be the Value of X? If
A man was born in the year 1896 A.D. If in the year x2 A.D. his age is x-4, the value of x is:
- 44
- 36
- 42
- 40
Answer: (1) 44
Explanation:-
According to the question,
X2 – 1896 = x – 4
x2 – 1896 – x + 4 = 0
x2 – x – 1892 = 0
x2 – 44x + 43x – 1892 = 0
x(x – 44) + 43 (x – 44) = 0
(x + 43)(x – 44) = 0
x – 44 = 0
x = 44
Hence, the value of x is 44.
