Question:
If two quantities p and q vary inversely with each other, then:
(a) p/q remains constant.
(b) p + q remains constant.
(c) p × q remains constant.
(d) p – q remains constant.
Solution:
(c) If two quantities p and q vary inversely with each other, then p x 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.
