Correct Answer: $2$

Solution : Given:
$\frac{(x+y)}{z}=2$
⇒ $y=2z-x$
⇒ $y-z=z-x$
Now, $[\frac{y}{(y-z)}]+[\frac{x}{(x-z)}]$
= $[\frac{y}{(z-x)}]+[\frac{x}{(x-z)}]$
= $[-\frac{y}{(x-z)}]+[\frac{x}{(x-z)}]$
= $[\frac{-y+x}{(x-z)}]$
= $[\frac{-(2z-x)+x}{(x-z)}]$ [After putting value of $y$]
= $[\frac{2(x-z)}{(x-z)}]$
= $2$
Hence, the correct answer is $2$.

Correct Answer: AB² + CD² = BC² + AD²

Solution : According to the question,

Using Pythagoras theorem,
In $\triangle$ABC 
AB² = AC² + BC² ...........................................(i)
In $\triangle$ACD
AD² = AC² + CD²
AC² = AD² – CD

Correct Answer: 1% decrease

Solution : For successive percentage change use the following formula,
Net percentage change = ($x+y+\frac{xy}{100}$)%, where $x$ and $y$ are percentage increases or decreases, if increases take positive and if decreases take negative. 
So, net percentage change = $- 10 + 10 + \frac{(-10) × (10)}{100}$
