**Solution:**

To find three odd numbers that sum up to 30, we need to consider the given odd numbers and determine which combination gives us the desired sum. Let's go through the step-by-step process to solve this problem.

**Step 1: List the Given Odd Numbers**
- 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29

**Step 2: Start with the First Number**
- Let's start by selecting the first number from the given odd numbers.
- We choose 1 as the first number.

**Step 3: Try Different Combinations**
- Now, we need to find two more numbers from the given list that, when added to 1, will give us the sum of 30.
- We can try different combinations to check if they satisfy the condition.

**Combination 1: 1, 3, 5**
- If we choose 1, 3, and 5, the sum is 1 + 3 + 5 = 9.
- This combination does not give us the desired sum of 30.

**Combination 2: 1, 3, 7**
- If we choose 1, 3, and 7, the sum is 1 + 3 + 7 = 11.
- This combination does not give us the desired sum of 30.

**Combination 3: 1, 3, 9**
- If we choose 1, 3, and 9, the sum is 1 + 3 + 9 = 13.
- This combination does not give us the desired sum of 30.

**Combination 4: 1, 3, 11**
- If we choose 1, 3, and 11, the sum is 1 + 3 + 11 = 15.
- This combination does not give us the desired sum of 30.

**Combination 5: 1, 3, 13**
- If we choose 1, 3, and 13, the sum is 1 + 3 + 13 = 17.
- This combination does not give us the desired sum of 30.

**Combination 6: 1, 3, 15**
- If we choose 1, 3, and 15, the sum is 1 + 3 + 15 = 19.
- This combination does not give us the desired sum of 30.

**Combination 7: 1, 3, 17**
- If we choose 1, 3, and 17, the sum is 1 + 3 + 17 = 21.
- This combination does not give us the desired sum of 30.

**Combination 8: 1, 3, 19**
- If we choose 1, 3, and 19, the sum is 1 + 3 + 19 = 23.
- This combination does not give us the desired sum of 30.

**Combination 9: 1, 3, 21**
- If we choose 1, 3, and 21, the sum is 1 + 3 + 21

It's impossible.30 is an even no.,the answer of 3 odd numbers must be odd!!
