If $50 %$ of $(x - y) = 30 %$ of $(x + y)$ , what percent of $x$ is $y$ ?
$33 \frac{1}{3} %$
$40 %$
$25 %$
$400 %$

Given: $50 %$ of $(x - y)$ = $30 %$ of $(x + y)$
$\Rightarrow \frac{50}{100} \times (x - y) = \frac{30}{100} \times (x + y)$
$\Rightarrow 50 x - 50 y = 30 x + 30 y$
$\Rightarrow 50 x - 30 y = 50 y + 30 y$
$\Rightarrow 20 x = 80 y$
$\Rightarrow \frac{1}{4} = y$
Hence y is $25 %$ of x.

If 50% of (x−y)=30% of (x+y), what percent of x is y?3313%40%25%400%

Given: 50% of (x−y) = 30% of (x+y)⇒50100×(x−y)=30100×(x+y)⇒50x−50y=30x+30y⇒50x−30y=50y+30y⇒20x=80y⇒14=yHence y is 25% of x.

$\Rightarrow \frac{1}{4} = y$
Hence y is $25 %$ of x.
