Question

Write the smallest 3-digit number which does not change, even if the digits are written in reverse order.

Answer 1

Find the smallest 3 digit number

The smallest 3-digit number which does not change the value when written in reverse order is $101$, but it changes when the digits are interchanged.

Hence $111$is the smallest 3-digit number which does not change value when digits are interchanged and even if written in reverse order.
