Answer 2

Answer:

Required number = 40

Step-by-step explanation:

Let the number be x.

According to the problem given,

$x \:increased \:by\:10 \\becomes \:\frac{5x}{4}$

$\implies x + 10 = \frac{5x}{4}$

$\implies x - \frac{5x}{4}=-10$

$\implies \frac{4x-5x}{4}=-10$

$\implies \frac{-x}{4}=-10$

$\implies x = (-10)\times \frac{-4}{1}$

$\implies x = 40$

Therefore,

Required number = 40
