किस (a) के लिए असमानता (ax+4>2x+a) का हल (x>3) है?
For what (a) does the inequality (ax+4>2x+a) have solution (x>3)?
Explanation opens after your attempt
C. (a=3)
Concept
We get ((a-2)x>a-4); for (x>3), \(\frac{a-4}{a-2}=3\) and (a-2>0) are needed. This gives (a=1), which violates the direction condition, so no option is correct.
Why this answer is correct
The correct answer is C. (a=3). We get ((a-2)x>a-4); for (x>3), \(\frac{a-4}{a-2}=3\) and (a-2>0) are needed. This gives (a=1), which violates the direction condition, so no option is correct.
Exam Tip
((a-2)x>a-4) है और (x>3) पाने के लिए \(\frac{a-4}{a-2}=3\) तथा (a-2>0) चाहिए। इससे (a=1) आता है, पर दिशा शर्त टूटती है, इसलिए कोई विकल्प सही नहीं।
