Question

Four fifth of a number is $4$ more than three fourth of the number. Find the number.

Answer 1

Let the number be $x$.

According to the question, lets form an equation

$\frac{4x}{5}-\frac{3x}{4}+4$

$\Rightarrow \frac{4x}{5}-\frac{3x}{4}=4$

$\frac{16x-15x}{20}=4$

$\Rightarrow \frac{x}{20}=4$

$\Rightarrow x=4\times 20$

$\Rightarrow x=80$

$\therefore$ The number is $x=80$.
