Satisfying Conditions (2)
Find the number that satisfies the mathematician’s conditions.
Each digit is a number out of 1, 3, 5,
7, and 9, and no 2 digits are the same.
The sum of the digits in the tens place
and ones place is 4.
The sum of the digits in the hundreds
place and tens place is less than 7.
Step 1. Out of the numbers 1, 3, 5, 7, and 9, the numbers that
can make the tens place and the ones place add up to
4 are and .
Step 2. Which number could be in the hundreds place?
Step 3. Find the number that satisfies the conditions.
