Answer:

iii) x1/x2=y2/y1

Step-by-step explanation:

Given that, x=k/y, where k is random constant

so, xy=k

thats means, for any pair like (x1,y1), (x2,y2)..... the xy product will always be a constant k.

So, x1y1=k

x2y2=k

.

.

.

xnyn=k

Clearly, x1y1=x2y2=x3y3=.......=k

And this only satisfies the 3rd option

x1/x2=y2/y1

=> x1y1=x2y2

So, (iii) is correct
