Question

which number has one digit that represents ten times the value of the digit to its right? a. 246,147 b. 327,449

Answer 1

To figure out the answer, let us get the value of each of the digits in the two options.

OPTION A:

$\begin{gathered} 2\Rightarrow200,000 \\ 4\Rightarrow40,000 \\ 6\Rightarrow6,000 \\ 1\Rightarrow100 \\ 4\Rightarrow40 \\ 7\Rightarrow7 \end{gathered}$

OPTION B:

$\begin{gathered} 3\Rightarrow300,000 \\ 2\Rightarrow20,000 \\ 7\Rightarrow7,000 \\ 4\Rightarrow400 \\ 4\Rightarrow40 \\ 9\Rightarrow9 \end{gathered}$

ANALYSIS:

The first option has no two subsequent numbers that satisfy the question.

Option B, though, has 2 numbers that do so:

$\begin{gathered} 400\text{ and 40} \\ \text{Since} \\ 40\times10=400 \end{gathered}$

ANSWER:

The correct option is OPTION B.
