I updated the puzzle to include this assumption contingency. The solution comes out the same regardless of weather you initially assume 5 odd and 1 even, or 5 even and 1 odd. In case you are curious: If all 6 hippos have odd or even weights, then you get no odd pair weights and 15 even pair weights. If you have 1 odd and 5 even, you get 5 odd pair weights and 10 even pair weights. If you have 2 odd and 4 even, you get 8 odd pair weights and 7 even pair weights. If you have 3 odd and 3 even you get 9 odd pair weights and 6 even pair weights. If you have 4 odd and 2 even you get 8 odd pair weights and 7 even pair weights again. If you have 5 odd and 1 even you get 5 odd pair weights and 10 even pair weights again, as you wisely pointed out. |
