yiu have to ad the sum of the digits so which one of these digit ad up to 3? 13, 15, 17, 19, 21, 23?
To find Mary's birthday, we need to consider the given clues:
1. Mary's birthday is between June 13 and June 23.
2. The date of her birthday is not an even number.
3. The sum of the digits is 3.
Let's analyze the given clues step by step to determine Mary's birthday:
1. Mary's birthday is between June 13 and June 23.
- This tells us that Mary's birthday must be a date between the 13th and the 23rd of June.
2. The date of her birthday is not an even number.
- From this clue, we can eliminate all even dates between the 13th and the 23rd. This means we should exclude the 14th, 16th, 18th, 20th, and 22nd.
3. The sum of the digits is 3.
- Based on this clue, we need to find a date whose digits, when added together, equal 3.
Now, let's go through the remaining dates and calculate the sum of their digits:
- The 13th: 1 + 3 = 4
- The 15th: 1 + 5 = 6
- The 17th: 1 + 7 = 8
- The 19th: 1 + 9 = 10
- The 21st: 2 + 1 = 3
- The 23rd: 2 + 3 = 5
From these calculations, we can see that the only date between the 13th and the 23rd that has a sum of digits equal to 3 is the 21st of June.
Therefore, Mary's birthday is on June 21st.
