1 2 3 4 5 6 7 8 9

Arrange these numbers into two separate groups so that they add up to same total.

Note : you cant turn 9 upside down and make it 6

You have to turn the 9 into a six.

Numbers 1-9 total 45, which can't be evenly split.

Making the 9 a 6 reduces that total by 3 to 42.

So we need two groups that each total 21.

1 2 3 4 5 6 and 6 7 8 should do it.

Or turn the 6 into 9, increasing the total by 3 to 48.

1 2 3 4 5 9 and 7 8 9 do it for that case.

i think that there is something wrong with the question....we can see that the total from 1 to 10 is 45 how can you divide 45 into two equal parts.....is there some cheating involved??i have got this -

18365 / 9274 they add up to 23 and 22...let me see what else i can do

this is what even i think how can you split 45 into two equal parts...P.S- he noted that we cant use 9 as 6...

Ah, I misread that. Good catch.

He did not say that you could not turn the 6 into a 9.

There is one solution in which you don't have to turn 6 into 9 or 9 into 6

The one who will give me that answer will be marked as best answer

So common guys give it a try

[Utkrisht123]

Group 1: 18,9,3,6

Group 2: 27, 4,5

both add up to 36

Good can you find one more

to get marked as best answer because there is one more competitor.

(sum=27)

12 6 9 | 3 4 5 7 8

12 4 5 6 | 3 7 8 9

3 4 5 6 9 | 12 7 8

...

(sum=36)

31 5 | 2 4 6 7 8 9

...

(sum=45)

31 5 9 | 24 6 7 8

...

A better question would be "How many different pairs of groups (with the same sum) can be formed?"
