MCQ
If two quantities $p$ and $q$ vary inversely with each other, then
  • A
    $\frac{\text{p}}{\text{q}}$ remains constant.
  • B
    $p+q$ remains constant.
  • ✓
    $p \times q$ remains constant.
  • D
    $p – q$ remains constant.
✓

Answer

Correct option: C.
$p \times q$ remains constant.
If two quantities $p$ and $q$ vary inversely with each other, then $p \times q$ remains constant. Since, in inverse proportion, an increase in $p$ cause a proportional decrease in $q$ and vice-versa.
