Question

Arrange the numbers in ascending order $23$, $35$, $19$, $64$, $51$.

• A. $64,51,35,23,19$
• B. $19,23,35,51,64$

Answer 1

The correct option is B $19,23,35,51,64$

All the number $23$, $35$, $19$, $64$, $51$ have same number of digits.

$\therefore$ We compare the numbers in terms of their respective place of digits.

$\to$ Larger the leftmost digit, larger will be the number.

The leftmost digits of each number are: $2,3,1,6,5$

Hence, the smallest number from the list is the number that starts with 1, i.e., 19.

Similarly, we figure out the next larger number and arrange in ascending order:

$19,23,35,51,64$
