QUESTION:

6 more the one-fourth of a number is two-fifths of the number. Find the number.

Let's assume:

The required number as x

GIVEN:

6 more the one-fourth of x = two fifths of x

$\frac{x}{4} + 6 = \frac{2x}{5}$

$\frac{x + 24}{4} = \frac{2x}{5}$

$5(x + 24) = 4(2x)$

$5x + 120 = 8x$

$3x = 120$

$x = \frac{120}{3}$

$x = 40$

$\bf \ \: { \therefore \:The \: required \: number \: is \: 40 }$
