Answer is
11.5 + 11.5 + 7
23 + 7 = 30
Choose 3 numbers= 13, 11 and 3!
We know 3!( 3 factorial) = 3×2×1= 6
13 +11 + 3! = 13 +11 +6 = 30
Another answer:
You can also add 15+9+3! = 15+9+6 = 30
No 9...Water melon is upside down. So, 6+11+13 = 30
9 numbered water melon is upside down... So, 6. Now 6+11+13 = 30
Hello Tarun Teja.
It is not possible because according to rule of mathematics sum of two odd numbers is always even, take any example. 3+5=8. 7+13=20 etc and then sum of one odd and one even number is always odd number hence in no combination odd and even can turn up to be even which is 30.
Hope you get it

I'm an experienced mathematics enthusiast with a demonstrated understanding of various mathematical concepts. My depth of knowledge in the field allows me to analyze and explain complex mathematical phenomena. Now, let's delve into the information related to the article about the sum of three odd numbers equaling 30.
The problem presented in the article is to find three odd numbers whose sum is 30. Several users have provided their solutions, and I will analyze and comment on each response:
-
Ansh's Answer (19th Feb, 2022):
- Ansh suggests the numbers 11.5, 11.5, and 7, claiming that their sum is 30.
- Comment: Ansh seems to have misunderstood the question. The numbers provided are not integers, and their sum is not 30.

Purushotam Singh Thakur's Answer (31st May, 2021):
- Purushotam suggests the numbers 13, 11, and 3!, where 3! denotes the factorial of 3.
- Comment: Purushotam correctly calculates the factorial and shows that the sum of these numbers is indeed 30.
-
Senthil Kumaran's Answers (31st May, 2021):
- Senthil provides two different sets of numbers: 6, 11, 13 and 6, 11, 13, claiming that both sums equal 30.
- Comment: Senthil's first set of numbers is incorrect as the sum is 30, not 30. The second set is also incorrect, as the sum is 30, not 30. There seems to be a misunderstanding or mistake in the responses.
-
Ashish Pal's Answer (24th Nov, 2019):
- Ashish dismisses the possibility of finding three odd numbers whose sum is 30. He argues that the sum of two odd numbers is always even, and the sum of one odd and one even number is always odd, making it impossible to obtain an even sum like 30.
- Comment: Ashish provides a valid mathematical explanation, reinforcing that finding three odd numbers whose sum is 30 is not possible.
In conclusion, Purushotam Singh Thakur provides a correct solution using the factorial concept, while the other responses contain errors or misunderstandings. The question challenges users to think critically about the properties of odd and even numbers, reinforcing the importance of mathematical reasoning in problem-solving.

So we can't add \[5\] odd numbers to get \[30\] because we get an odd number and 30 is an even number. Final answer: if we add \[5\] odd numbers then we get an odd number and in question, \[30\] is given which is an even number.
Is 30 odd or even? ›
Is 30 Even or Odd? Yes, 30 is an even number because it is divisible by 2. We can also check this by observing the last digit of 30 which is zero. If the last digit of a number is 0, 2, 4, 6, or 8 it is an even number.
Can 3 odd numbers add up to an even number? ›
No. Note that any odd number N can be written in the form N=2a+1 N = 2 a + 1 for some integer a , then adding three of these becomes 2(a+b+c)+3 2 ( a + b + c ) + 3 which is always odd as the sum of an even number and an odd number is always odd (which is something you should definitely prove, yourself).
