Question

Which one of the following is the smallest numeral $?$

• A. $15673$
• B. $15700$
• C. $15198$
• D. $15623$

Answer 1

The correct option is C

$15198$

Finding the smallest numeral:

Rule 1.- A numeral containing more digits represents a greater number

Rule 2- If the two numerals contain the same number of digits, we compare them by their left-most digit. if the left-most digits are also the same, we compare them by their next digits from the left, and so on.

In this question all the numbers have two left most digits same, so we will compare the third left most digit

$$\begin{gathered} \Rightarrow 7>6>1 \\ \Rightarrow 15700>15673>15623>15198 \end{gathered}$$

Thus, the smallest numeral is $15198$.
