In this river scenario, there's a bridge. With this bridge, we must weigh the sheep on both sides of the river to find the wolf, along with the hint that the wolf is lighter than the sheep.
Here are hints for solving the smaller stages within question 13.
Answer to River Crossing IQ question number 13.1
Weigh 1,2,3 on the left side and 5,6,7 on the right side:
- If they're equal, weigh 4 and 8, the lighter one is the Wolf.
- If one side is heavier and the other lighter: Weigh 3 sheep from the lighter side together --> weigh 2 against each other, the lighter one is the wolf --> if they're equal, then the remaining one is the wolf
Answer to River Crossing IQ question number 13.2: We have 12 sheep numbered from 1 to 12
Round 1: Weigh sheep 1, 2, 3, 4 against 5, 6, 7, 8
Round 2: Weigh sheep 9, 10, 11, 5 against 1, 2, 7, 8
- Case 1: Both rounds weigh the same --> sheep number 12 is the fake sheep
- Case 2: Round 1 equals, round 2: left side lighter
+ Weigh round 3: 9 and 10
If < : the fake sheep is number 9
If > : the fake sheep is number 10
If = : the fake sheep is number 11
- Case 3: Round 1 equals, round 2: left side heavier
+ Weigh round 3: 9 against 10
If < : the fake sheep is number 9
If > : the fake sheep is number 10
If = : the fake sheep is number 11
- Case 4: Round 1: left side lighter, round 2 equals
+ Weigh round 3: 3 and 4
If < : the fake sheep is number 3 or 4 and the fake sheep is lighter => the fake sheep is number 3
If > : the fake sheep is number 3 or 4 and the fake sheep is lighter => the fake sheep is number 4
If = : the fake sheep is number 6
- Case 5: Round 1: left side heavier, round 2 equals
+ Weigh round 3: weigh 3 against 4
If < : the fake sheep is number 3 or 4 and the fake sheep is heavier => the fake sheep is number 4
If > : the fake sheep is number 3 or 4 and the fake sheep is heavier => the fake sheep is number 3
If = : the fake sheep is number 6
