What odd numbers can be used to fill the blanks? __ + __ + __ = 30.

Solution:

Let k be any real number.

So, (2k + 1) will be an odd number & 2k will be an even number.

Let n, m be some other random real numbers.

If we add (2k + 1), (2m + 1), (2n + 1) (all being odd numbers)

We get, 2k + 2m +2n + 3

We know that,

2k, 2m, 2n are even numbers.

So, 2k + 2m + 2n is even and when you add an odd number to an even number we get an odd number.

Hence the solution is not possible.

What odd numbers can be used to fill the blanks? __ + __ + __ = 30.

Summary:

There’s no solution as the sum of 3 odd numbers can’t be even.
