MCQ
If $x > 7$ then which is impossible?
  • A
    $x > 4$
  • ✓
    $x < 6$
  • C
    $x > 9$
  • D
    $x < 14$
✓

Answer

Correct option: B.
$x < 6$
$x > 7$ and $7 > 4$
$\Rightarrow x > 7 > 4$
$\Rightarrow x > 4.$
If $x > 7$ then $x$ cannot be less than $6.$
If $x = 11$ then $x > 7$ and $x > 9.$
If $x = 11$ then $x > 7$ and $x < 14.$
