1 duck saw 4 elephants as it was going toward the river.
Every elephant noticed 2 monkeys going to the river.
Every monkey was carrying 1 dove in its paws.
How many animals are going to the river?
Five animals are moving toward the river.
Here's a detailed answer:
1 duck noticed 4 elephants as it was going toward the river. Hence, 1 animal (the duck) is moving to the river.
The 4 elephants saw 2 monkeys going walking toward the river. Now comes the tricky part. You may think that each elephant saw 2 different monkeys walking toward the river. So you would conclude that 4 x 2 = 8 monkeys were going to the river.
However, the task does not explicitly say that each elephant saw DIFFERENT monkeys. In fact, you can logically infer that the elephants saw the SAME 2 monkeys. Hence, we only have 2 additional animals (monkeys) moving toward the river.
Since every monkey was carrying 1 dove, the 2 monkeys were carrying 2 doves in total.
Summing up, we have 1 duck, 2 monkeys, and 2 doves moving to the river. 1 + 2 + 2 = 5 animals.
The Chicken, Fox, and Corn Riddle
Riddle:
You've got a sack of corn, a chicken, and a fox. You have to cross a river, but you can only carry them one at a time. If you leave the chicken with the sack of corn, the chicken will eat the corn. If you leave the fox alone with the chicken, the fox will eat the bird.
How can you get all three things across the river safely?
Cross the river with the chicken, then go back and carry the corn over the river. However, instead of leaving the corn with the bird, return together with the chicken. Cross the river for the third time with the fox, leaving the chicken behind. Leave the fox with the sack of corn, and return for the last time to get the chicken. Done!
