Correct Answer: $x^2y^2$

Solution : Let the mean proportion be $a$
Given numbers,
$x^3y$ and $xy^3$
⇒ $a^2=x^3y\times xy^3$
⇒ $a^2=x^4y^4$
⇒ $a=x^2y^2$
Hence, the correct answer is $x^2y^2$.

Correct Answer: $\frac{n-\sqrt{n^2-m^2}}{m}$

Solution : Given that $\cos 48^{\circ}=\frac{m}{n}$,
We know that $\sec 48^{\circ}=\frac{n}{m}$,
We know that $\tan \theta=\sqrt{\sec^2 \theta-1}$,
Now, $\cot 42^{\circ}=\tan 48^{\circ}=\sqrt{\sec^2 48^{\circ}-1}=\sqrt{\left(\frac{n}{m}\right)^2-1}=\sqrt{\frac{n^2}{m^2}-1}=\frac{\sqrt{n^2-m^2}}{m}$
So, $\sec 48^{\circ}-\cot 42^{\circ}=\frac{n}{m}-\frac{\sqrt{n^2-m^2}}{m}=\frac{n-\sqrt{n^2-m^2}}{m}$.
Hence, the correct answer is $\frac{n-\sqrt{n^2-m^2}}{m}$.
