Solve it...
[ ] + [ ] + [ ] = 30 fill the brackets using below numbers ( 1, 3, 5, 7, 9, 11, 13,15 ) you can repeat the numbers... Please help me! Many more people unsucceed to solve it
since all the numbers are odd, there is no way adding three of them can give an even result.
7+9+15
To solve the equation [ ] + [ ] + [ ] = 30 using the numbers 1, 3, 5, 7, 9, 11, 13, and 15, we need to find a combination of these numbers that adds up to 30. Here's how we can do it:
Since you can repeat the numbers, let's start by using the largest number available, 15. We can use it in two of the three brackets, like this:
15 + 15 + [ ] = 30
Now we can see that we need the remaining two numbers to add up to 30 - 15 - 15 = 0.
To achieve this, we need to select two numbers with a sum of 0. The only two numbers in the list provided that can sum up to 0 are -15 and 15:
15 + 15 + (-15) = 15 + 15 - 15 = 30
Therefore, the solution is:
[15] + [15] + [-15] = 30.
By using two 15's and one -15, the equation is balanced, and it equals 30.
