BEST ANSWER WILL BE GET THE BRAINLIEST​

Answer 1

let the no be 10x + y

so 10x + y = 3(x+y)

7x = 2y

if x= 2 ,y = 7 then 27= 3(2+7)

the no is 27

Answer 2

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

Number is 27

$\mathfrak{\large{\underline{\underline{Given:-}}}}$

Let 10x + y be a number,

such that, 10x + y = 3(x + y)

$\mathfrak{\large{\underline{\underline{</strong><strong>T</strong><strong>o</strong><strong> </strong><strong>find</strong><strong>:-}}}}$

The number = ?

$\mathfrak{\large{\underline{\underline{Solution:-}}}}$

According to question:-

$\implies$ 10 x + y = 3( x + y)

$\implies$ 10 x + y = 3x + 3 y

$\implies$ 10 x - 3x = 3y - y

$\implies$ 7 x = 2 y

$\implies$ $\bold{</strong><strong> \frac{x}{y} = \frac{7}{2} </strong><strong>}$

$\implies$ x = 7 , y = 2

then, required number is given by :- 10 y + x

= 10 × 2 + 7

= 20 + 7

= 27

hence, required number is 27.
