Question

A number, when added to its two-third, gives $55$. Find the number.

Answer 1

According to the question,

let the number be $x$

then $x+\left(2/3\right)x=55$

$\frac{3x+2x}{3}=55$

$\left(\frac{5}{3}\right)x=55$

$x=55\times \frac{3}{5}$

$x=11\times 3$

$x=33$

Hence the number is $33$
