Answer 1

Step-by-step explanation:

answer is 3rd 95 please give me brainlest

Answer 2

$Let \: a \: number \: be \: 'x'$

/* According to the problem given */

$\frac{4x}{5} = 60\% \:of \: x + 25$

$\implies \frac{4x}{5} = \frac{60}{100} \times x + 25$

$\implies \frac{4x}{5} = \frac{3}{5} \times x + 25$

$\implies \frac{4x}{5} - \frac{3x}{5} = 25$

$\implies \frac{4x-3x}{5} = 25$

$\implies \frac{x}{5} = 25$

$\implies x = 25 \times 5$

$\implies x = 125\: --(1)$

$Now, 70\% \: of \: x$

$= 70\% \: of \: 125$

$= \frac{70}{100} \times 125$

$= 87.5$

Therefore.,

$Option \: { ( 1 ) } \: is \: correct$
