If two quantities p and q vary inversely

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.
