$a,b,c$ are $3$ differnt digits.Let,$\overline {abc}=100a +10b +c$
If $ba×c=abc$ and $abc$ is smallest such number then what is the value of $9c+8b+a$?
Note
It is self made and easy alphamatics.
Hint
Start from $123$.

Yes,$a=1$,$b=2$,$c=6$ So,the answer is $71$.Now think deeply and you will understand the question.
