I am a 5-digit number.
1. My ten thousands digit is 3.
2. My ones digit is the smallest odd single-digit number.
3. My hundreds digit is three times my ten thousands digit.
4. My tens digit is two less than my hundreds digit.
5. The sum of my thousands digit and my ones digit equals my tens digit.
What number am I?
Let’s solve this step by step using the given information:
1. The ten thousands digit is 3.
2. The ones digit is the smallest odd single-digit number, which is 1.
3. The hundreds digit is three times the ten thousands digit: 3 × 3 = 9.
4. The tens digit is two less than the hundreds digit: 9 – 2 = 7.
5. The sum of the thousands digit and the ones digit equals the tens digit.
We know the tens digit is 7, and the ones digit is 1. So, the thousands digit must be: 7 – 1 = 6.
Therefore, the digits from left to right are:
– Ten thousands: 3
– Thousands: 6
– Hundreds: 9
– Tens: 7
– Ones: 1
The mystery number is 36971.
