Question

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

Answer 1

Answer:

101

Step-by-step explanation:

See, if we start thinking from smallest 3 digit number and its reverse order, we would get:

100 - 001 not same

101 - 101 same

∴ 101 is the smallest 3- digit number which does not change even if the digits are written in reverse order.​

Or you can remember this point that:

the smallest n- digit number which does not change even if the digits are written in reverse order is {(smallest n- digits number) + 1}

Example : lets find for 5 digit number

10000 - 00001 not same

10001 - 10001 same

You can observe here that 100001 is (smallest 5- digits number) + 1

Similarly, For 6 digit - 100001

For 1 digit = 1,2,3,4,5,6,8,9 all have same reverse

So, this formula is applicable fo 1+ digits

Lets take for 2 digit

that is 11 which is again in form of (smallest 2- digits number) + 1

Hope, you got it:-))
