A,B,C and D are four different physical quantities having different dimensions. None of them is dimensionless. But we know that the equation AD = Cln(BD) holds true. Then which of the combination is not a meaningful quantity?

@Vijay

A.D= C \ln \left ( B.D \right )

Hence dimensionless

\left [ B \right ]= \left [ \frac{1}{D} \right ]...............(1)

&   \left [ A.D \right ]= \left [ C \right ]...............(2)

Relevent Concept here is :

Dimension -

The power to which fundamental quantities must be raised in order to express the given physical quantities.

in the \frac{A-C}{D} the dimensions of A are not same as dimensions of C meaningless
