2 by 3 of a number is less than the original number by 20. Find the number​.

$\bf\orange{AnsweR:-}$

Let the number be X.

According to the given condition,

$\longrightarrow\bf{\dfrac{2}{3}\:of\:X=X-20}$

$\longrightarrow\bf{\dfrac{2X}{3}=X-20}$

$\longrightarrow\bf{2X=3\times(X-20)}$

$\longrightarrow\bf{2X=3X-60}$

$\longrightarrow\bf{2X-3X=-60}$

That is,

$\longrightarrow\bf{60=3X-2X}$

$\longrightarrow\bf{X=60}$

Then the required number is 60.
