Answer 1

Answer:

Answer:

$\pink{ \sf \: 25\% \: of \: x\: is\: y}$

Step-by-step explanation:

$\sf \: \begin{gathered} \sf \: 50\% \: of\: (x-y)\\ \sf=30\% \: of \: (x+y)\end{gathered}$

$\begin{gathered}\implies \sf \: \frac{50}{100}\times (x-y)\\= \sf \: \frac{30}{100}\times (x+y)\end{gathered}$

/Multiply both sides by 10, we get

$\sf \: \implies 5(x-y)=3(x+y)$

$\sf \: \implies 5x-5y=3x+3y$

$\sf \: \implies 5x-3x = 3y+5y$

$\sf \: \implies 2x = 8y$

$\sf \: \implies x = \frac{8y}{2}$

$\sf \red{\implies x = 4y}$

$\sf \: \implies y = \frac{1}{4}\times x$

$\sf \: \implies y = \frac{1}{4}\times 100\%\: of \: y$

$\sf \: \implies y = \left(\frac{100}{4}\right)\%\times x$

$\sf \: \implies y = 25\%\: of \: xq$

Therefore,

$\boxed{ \red{ \sf \frak{25\% }\: of \: x\: is\: y}}$
