Question

Which $3$ digit numbers can be formed, using three digit number $921$? (Without repeating the numbers in three digit)

• A. $219,199$ and $912$
• B. $219,129$ and $912$
• C. $219,119$ and $912$
• D. $219,129$ and $212$

Answer 1

The correct option is B $219,129$ and $912$

$921$ can be written using the general form $abc=100\times a+10\times b+c$
By changing the alphabetic orders of $a,b,c$, we get $5$ more three digit numbers from $921$.
Here, $219,129$ and $912$ are formed from the $3$ digit number $921$.
