Answer 2

Answer:

The number can be $141,582$.

Step-by-step explanation:

It is given that there is a three digit number.

The second digit is four times the third digit.

The first digit is three less than the second digit.

We need to determine the number.

Let ones digit be $z$, tens digit be $y$ and hundredth digit be $x$.

The number will be $xyz$.

According to question.

$y=4z$

and

$x=y-3=4z-3$

If $z=1$, $x=4(1)-3=1$ and $y=4(1)=4$

Hence, number is $141$.

If $z=2$, $x=4(2)-3=5$ and $y=4(2)=8$

Number is $582$.
