Answer 2

Answer:

Heya mate...........

Here's your answer :

The number is 150.

Step-by-step explanation:

Let the number be x.

Then, according to the question:

$= x( \frac{1}{5} ) + 20 = x( \frac{1}{3} ) \\ = \frac{x}{5} - \frac{x}{3} = - 20 \\ (transposing \: \frac{x}{3} \: from \: right \: to \: \\ left \: and \: 20 \: from \: left \: to \: right) \\ = \frac{3 x - 5x}{15} = - 20 \\ = \frac{ - 2x}{15} = - 20 \\ = - 2x = - 20 \times 15$

$= - 2x = - 300 \\ = x = \frac{ - 300}{ - 2} \\ = x = 150 \\ ( both \: negative \: signs \: cancel \\ \: each \: other)$

Therefore, the required number is 150.
