Hi I am a grade 5 student and am having trouble with this question

What number could it be?

It is between 12000 and 13000
Its hundreds, ten and ones digits are all odd
the sum of all its digits is 12


Thank you
Jonathan

Hi Jonathan.

We have two replies for you

There are many answers to your question.

If the sum of the digits is 12 and the first two digits are 12, then
the sum of the last three digits is 12 - 1 - 2 = 9.

The last three digits are odd and they add up to 9. But there are
many ways to do this:
7+1+1
1+1+7
1+7+1
3+3+3
5+1+3
5+3+1
1+3+5
1+5+3
3+1+5
3+5+1

Each of these will give you an answer that satisfies all the conditions.

Hope this helps,
Stephen La Rocque.

Some say 12333, others say 12171, yet others say 12531 and others 12432. Who to believe?
