i am a number between 20 and 30.when you put me into 6 equal groups;there is an even number in each group and 1 is left over.what number am i
It has to be a number X such that X-1 is divisible by 4, an even number of times.
How about 25?
my answer is 25
My answer was 25.
I don't know cam you explain me
Can u explain to me
To find the number, you can start by thinking about the properties of the number when divided equally into 6 groups.
We know that there is an even number in each group, and there is one left over. This means the number must be odd.
Given that you are a number between 20 and 30, we can narrow down the possibilities to 21, 23, 25, 27, and 29.
Now let's divide each of these numbers into 6 equal groups and see if there is one left over:
- For number 21, if we divide it into 6 equal groups, we get 3 members in each group and 3 left over. So, 21 is not the answer.
- For number 23, if we divide it into 6 equal groups, we get 3 members in each group and 5 left over. So, 23 is not the answer.
- For number 25, if we divide it into 6 equal groups, we get 4 members in each group and 1 left over. So, 25 is the answer!
Thus, if you are a number between 20 and 30 and there is an even number in each of the 6 groups with 1 left over, you must be the number 25.
