Odd numbers help

[Sarmadas]

i want know the 5 distinct odd numbers from 1 to 20 the sum of these 5 numbers must be Equal to 50 Is it possible

[Disch]

No it is not possible.

odd+odd = even
odd+even = odd

therefore:

odd*odd = odd
odd*even = even


You are trying to find numbers which satisfy
odd * 5 = 50

However since 5 is odd, this means you are doing odd*odd, which means the result will be odd... and 50 is even.


Long story short... the sum of any 5 odd numbers is going to be odd. There is no solution to this problem.


EDIT: though I'm not entirely sure what this has to do with C++.....
