Solution

The correct option is B $z = 2 x$
It is $y % o f z = 2 (\begin{matrix} x % o f y \end{matrix})$
$\Rightarrow \frac{y z}{100} = \frac{2 x y}{100}$
$\Rightarrow z = 2 x$

Q32. If x% of y is 100 and y% of z is 200, then find a relation between x and z.

Δ_{1} = ∣ ∣ ∣ ∣ \begin{matrix} x - y - z & 2 x & 2 x 2 y & y - z - x & 2 y 2 z & 2 z & z - x - y \end{matrix} ∣ ∣ ∣ ∣

Δ_{2} = ∣ ∣ ∣ ∣ \begin{matrix} x + y + 2 z & x & y z & y + z + 2 x & y z & x & z + x + 2 y \end{matrix} ∣ ∣ ∣ ∣

\frac{x}{2 y + z - x} = \frac{y}{2 z + x - y} = \frac{z}{2 x + y - z}

x + y + z \neq 0

If $x, y, z \in R^{+}$ then $\frac{x y}{x + y} + \frac{y z}{y + z} + \frac{x z}{x + z}$ is always
