Answer 2

Answer -

• The number = 25.

To find -

• The number.

Step-by-step explanation -

Let the number be "x".

Then -

$\mapsto \sf Three\!-\!fifth \: of \: the \: no. \: will \: be : \dfrac{3}{5}x$

Given that -

• Two more than three fifth of the number is 17.

Therefore -

$\implies \mathfrak{\dfrac{3}{5}x + 2 = 17}$

$\implies \mathfrak{\dfrac{3x}{5} + 2 = 17}$

$\implies \mathfrak{\dfrac{3x}{5} = 17 - 2}$

$\implies \mathfrak{\dfrac{3x}{5} = 15}$

$\implies \mathfrak{3x = 15 \times 5}$

$\implies \mathfrak{3x = 75}$

$\implies \mathfrak{x = \cancel{\dfrac{75}{3}}}$

$\implies \mathfrak{x = 25}$

Hence -

• The number is 25.
