Hi dudes,

If I am right, the answer should be:

123456789 and 246913578

That decimal (.) was to avoid sajha's making first letter graphical.

If the decimal was part of solution, then second number wouldn't be double the first number.

It asks to use all 9 digits, and each of them only once.

So, I think I am not wrong.

Garrrate! woohoo @ debonair.

But, the challenge is "Using all the digits 1 to 9, each once only, make two numbers". So, the question is ... what does OcRam mean by "each once only, make two numbers"? It is such a dubious phrase.

Spiderman, debonair is right as long as we consider "each once only, make two numbers"phrase as we may create replica of 1-9 to create two different numbers. But apparently, I do not think that is what OcRam means.

considering how ocram has stated the question (unless otherwise stated) i think praksah je answer is the most correct one. or else ocram needs to mention the number of digits in each number and its not clear whether each digits should be used only once in both number or only one of the two numbers. btw MM don't you think youre making it more complicated LOL

Hey guys you all are giving the wrong answers. You may not have understood the question clearly. I know the answer so I am clarifying the question. You should have all digits consisting of 1 to 9 without repitition. You cannot take only some (say 13458 ). The number should contain nine digits consisting 1 to 9 and the double of it also should have 9 digits between 1 to 9 without repitition in both.

so you cannot say 6729 and its double is 13458 or similar which has less than nine digits.

The answer given by debonair is right.

123456789 and its double 246913578 each with 9 digits and no repitition

Repeating:

First Set:

123456789 x2=246913578

Second Set:

213456789x2=426913578

Is it correct?
