# Let us write whet

(i) Given:  xy = k = non zero constant

Hence, given statement is not true.

(ii) Given: x z , y z

It can be written as,

x = k y, y = m z

where k, m are constant of variations.

Put the value of y in x,

We get,

x = k m z

x z

Multiply both sides by y.

We get,

xy yz

Hence, given statement is not true.
