High math skills are required to solve this puzzle… Fill in the three boxes below using any of the following numbers: 1, 3, 5, 7, 9, 11, 13, 15.
You are allowed to repeat the numbers.
Adding an odd number of odd numbers results in an odd number. Therefore, it is impossible to achieve a sum of 30 by adding three odd numbers. However, through creative lateral thinking, it is possible to obtain this result using a workaround. Here is an approach that employs the combination formula known as “n choose r” or “C(n, r)”:
Other possible solutions include: 9.3 + 5.7 + 15 = 30 11 + 13 + 3! = 30
