Let the eightNo be x.

we call it as

$\frac{1}{8} x$,$\frac{1}{12} x$,$\frac{1}{20} x$

SUM of these Nos is 31

so

$\frac{1}{8} x + \frac{1}{12} x + \frac{1}{20} x = 31$

Take LCM

$\frac{15x + 10x + 6x}{120} = 31 \\ 15x + 10x + 6x = 3720 \\ 31x = 3720 \\ x = \frac{3720}{31} \\ x = 120$

So the Nos is $</strong><strong>\</strong><strong>h</strong><strong>u</strong><strong>g</strong><strong>e</strong><strong>\red{\boxed{\sf 120}}$
