I'm a 4 digit number with no 2 digits the same.
My ones digit is twice my thousands digit and 1 less than my tens digit.
My hundreds digit is the difference between my tens digit and my thousands digit.
My thousands digit is an odd number less than 6.
What number am I?
XXXX
axx(2a)
a(b-a)b(2a)
and 2a=b-1
so a cannot be 1 as that would make the hundreds digit the same as the ones
if a is 2, then 2a=4, and b=5, and the thousands digit is also4.
if a is 3, then 2a=6, and b=7, and thousands is 4 (7-3)
number is 3476
lets see if there are others.
if a is 4, 2a is 8, and b=9, and b-a is 5: solution 4598
a cannot be greater than 4, as the ones digit has to be twice a.
SO, two solutions: 3476 and 4598
check all this.
what is the value of the underline digit 6.... 4,600,028
how can you explain the difference between 120-70 using mental math
what is the fist anwer.
I am a 3-digit number. My ones digit is three times my tens digit. Two times the sum of my tens and ones digits equals my tenths digit. What am I ?

To find the 4-digit number described in the question, we can go through the given clues step by step.
1. The thousands digit is an odd number less than 6.
The possible options for the thousands digit are: 1, 3, or 5.
2. The ones digit is twice the thousands digit and 1 less than the tens digit.
If the thousands digit is 1, the ones digit is 2 and the tens digit is 3.
If the thousands digit is 3, the ones digit is 6 and the tens digit is 7.
If the thousands digit is 5, the ones digit is 10, which is not possible since it's a 4-digit number.
3. The hundreds digit is the difference between the tens digit and the thousands digit.
If the thousands digit is 1 and the tens digit is 3, the difference is 2, so the hundreds digit is 2.
If the thousands digit is 3 and the tens digit is 7, the difference is 4, so the hundreds digit is 4.
Combining the digits, we find two possible numbers: 1234 or 3746. However, since the question states that no two digits are the same, the correct answer is 3746.
Therefore, the number is 3746.
