OFFICIAL EXPLANATION


We know $\(\mathrm{x}<\mathrm{y}<\mathrm{z}\)$ are the length of the edges of a Cuboid.

Volume of a Cuboid $\(=\)$ Length $\(\times\)$ Breadth $\(\times\)$ Height

So, the volume of Cuboid having edges $\((x+10), y \& z\)$ is $\((x+10) \times y \times z=x y z+10 y z\)$ \& the volume of the Cuboid having edges $\(x, y \&(z+10)\)$ is $\(x \times y \times(z+10)=x y z+10 x y\)$

The comparison between $\(x y z+10 y z \& x y z+10 x y\)$ is same as comparing $\(10 y z \& 10 x y\)$ i.e. comparing z with x .

As $\(Z>x\)$, column $\(A\)$ has higher quantity when compared with column $\(B\)$.

Hence the answer is (A).
