Answer 2

Answer:

$\red { Required \: number }\green {= 30 }$

Step-by-step explanation:

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

/* According to the problem given

$x \: added \: to \: \frac{x}{2} = 45$

$\implies x + \frac{x}{2} = 45$

$\implies \frac{2x+x}{2} = 45$

$\implies \frac{3x}{2} = 45$

$\implies x = 45 \times \frac{2}{3}\\= 15 \times 2 \\= 30$

Therefore.,

$\red { Required \: number (x) }\green {= 30 }$
