Question

Density is best given by _______

(a) Product of volume and density

(b) Ratio of mass to Volume

(c) Addition of mass and density

(d) Subtraction of mass and density

The question was posed to me in an online interview.

The doubt is from Centroid of a Body topic in division Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

The correct answer is (b) Ratio of mass to Volume

To explain I would say: The density is the ratio of the mass to the volume of the body. Thus arranging them and the volume is said to be a the ratio of mass to density. This equation is generally used in the calculations of the centroid of the body.
