MCQ
Which quantities in the previous question vary inversely with each other?
- A$x$ and $y$
- B$p$ and $q$
- C$r$ and $s$
- ✓$u$ and $v$
✓
Answer
Correct option: D.
$u$ and $v$
D. $u$ and $v$
Solution:
$p1^22^23^24^2$
$q1^32^33^34^3$
If we multiply r with $2.5$ & s with $2.5,$ we will get the given result. In option (d),
If $u = 2,$ then $v = 18$
If $u = 4,$ then $v = 6$
If $u = 9,$ then $v = 4$
If $u = 12,$ then $v = 3$
It show, when $u$ increases, then $v$ decreases. Hence, it is inversely with each other.
