Question

There is a four digit number with a condition whose last digit is double of first and second and third are same digit and last two digit are double of first two digit

Answer 1

It’s not possible. If the last is twice the first, then our option are:

1__2

2__4

3__6

4__8

If the two middle digits are the same, then I cannot add the same number to 1 as I add to 2 and get the same answer.

There is no number that can be added to two different numbers to get the same answer.

Hence, no solution.
