Which quantities in the previous question vary inversely with each other?
A. x and y
B. p and q
C. r and s
D. u and v
In option (b),
If we multiply p and q with 1,2,3 and 4, we get the given result. But it is not given inversely.
In option (c),
If we multiply r with 2.5 and s with 2.5, we will get the given result.
In option (d),
If u = 2, then v = 18
If u = 4, then v = 9
If u = 6, then v = 6
If u = 9, then v = 4
And if u = 12, then v = 3
It shows, when u increases, then v decreases.
Hence it is inversely with each other.
