Question

Rearrange the digits of $1,02,35,007$ to get the largest and the smallest number. The difference between the place values of $2$ in these two numbers is

• A. $0$
• B. $8000$
• C. $20000$
• D. $18000$

Answer 1

The correct option is D $18000$

By arranging the digits in the descending order, we will get the largest number.

The largest number is $7,53,21,000$.

By arranging the digits in the ascending order, we will get the smallest number.

However, if zeros are placed in the beginning of a number, it loses is significance.

Hence, the smallest number is $1,00,02,357$.

Difference in the place values of $2$
$=20000-2000=18000$

So, option D is correct.
