Krishnakumar, Raghunandan, Chinnan and Aibak had an interesting discussion on the following:
Find the range of real values of x not satisfying even one of the inequalities 6x - 8 > 40 and 9x - 19 > 80"
Choose the correct answer:  A) x greater than 8  B) x lesser than or equal to 8  C) x lesser to 8  D) x greater than or equal to 8  E) None of these
6x – 8 &gt; 40 =&gt; 6x &gt;48 =&gt; x &gt; 8 ...(1)   And 9x – 19 &gt; 80 = &gt; 9x &gt;99 =&gt; x &gt;11 ...(2)   For both the inequalities to hold true, x should be greater than 11, and for values of x greater than 8, at least the first inequality (1) will be satisfied.   For x not to satisfy both the inequalities, it has to be equal to or lesser than 8.   Therefore, our answer is x lesser than or equal to 8   ANSWER:x lesser to 8
