It's impossible to restate the question: a + b + c = 30, where a, b and c are odd numbers up to and including 15. When you add two odd numbers together, you get an even number. For example, let's say x = 2n + 1 and y = 2k + 1. x + y = 2(n + k) + 2 = 2(n + k + 1). x + y has a factor of two hence x + y is even. When you subtract an even number from another even number, you simply get an even number. Thus one of a, b or c has to be even. But we can only use odd numbers, hence there is no solution. Impossible At least, that's what I think 1 Like |

BeanMachine:correct but your grammar too much, just simply say the sum of 3 odd numbers cannot give you an even number. So its impossible. 1 Like |
