Answer 2

Step-by-step explanation:

i) x and y vary inversely to each other

$x∝ \frac{1}{y} \\ = > x = \frac{k}{y} \\ (where \: k \: = \: constant) \\ = > xy = k \\ = > xy = constant$

Therefore, i) belongs to (c)

ii) Mathematical representation of direct variation of quantities m and n

$m∝n \\ m = kn \\ \frac{m}{n} = k \\ \frac{m}{n} = constant$

There seems to be no option in Column II matching with ii) but there is one similar to it, which is a).

There seems to be no option in Column II matching with ii) but there is one similar to it, which is a).Therefore, ii) belongs to (a)

iii) Mathematical representation of inverse variation of quantities p and q.

$p∝ \frac{1}{q}$

Therefore, iii) belongs to (d)

iv) If x and y vary inversely then on decreasing x

$x∝ \frac{1}{y} \\ y \: will \: increase$

Therefore, (iv) belongs to (b)
