# If $P, Q, R$ are physical quantities, having different dimensions, which of the following combinations can never be a meaningful quantity?

$(P-Q)/R$

##### SOLUTION
As per the principle of homogeneity of dimension, addition subtraction or equality between two quantities of different dimensions are not possible while division and multiplication are possible.
Hence option A is correct.

You're just one step away
