Question 14

If two quantities p and q vary inversely with each other, then

(a) $\frac{p}{q} r e m a i n s c o n s t a n t$
(b) $(p + q) r e m a i n s c o n s t a n t$
(c) $(p \times q) r e m a i n s c o n s t a n t$
(d) $(p - q) r e m a i n s c o n s t a n t$

Open in App

Solution

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.
Hence, option (c) is correct.
