Concept
The inequality gives (x<4), so (x=4) is not included. In a strict inequality, the boundary value is not a solution.
Why this answer is correct
The correct answer is A. (x=4). The inequality gives (x<4), so (x=4) is not included. In a strict inequality, the boundary value is not a solution.
Exam Tip
असमानता से (x<4) मिलता है, इसलिए (x=4) शामिल नहीं है। कठोर असमानता में सीमा मान हल नहीं होता।
