3. Grandma's Riddle
You took a tiger, a goat, and a cauliflower on a trip with you (the reason why you did this is none of our business). You need to cross a river using a very small boat that can only carry you and one of the three possessions you have. You can't leave the tiger and the goat on the river bank, because the tiger will gobble the goat up. Similarly, you can't take the tiger, as the goat will eat the cauliflower while you are away from the bank. How will you carry all three things across the river?
First, take the goat with you, leave it on the other bank. Come back alone. Then take the tiger, leave it on the other bank and come back with the goat. This time, leave the goat behind and row the cauliflower across. Come back alone. Now, you can take the goat and cross the river for one last time. The puzzle is solved!

5. Back on Feet Again
You are staying at Four Seasons Hotel Los Angeles in Beverly Hills. Five beauty queens are staying at it, too. Each of them has booked five suits and each suit is occupied by five little annoying dogs. Each of these dogs has five little toy tigers. Each toy tiger and each little dog has four legs. How many legs are there in the hotel?
The answer is 3012. 5 suits for each of the 5 beauty queens make 25 rooms. There are 5 little dogs in each of the 25 suits; 25x5=125 little dogs total. The number of little toy tigers is 625 (5 per each of the 125 little dogs). There are 125+625=750 four-legged objects, both animate and inanimate, in all of the suits, and they have 750x4=3000 legs. Add the 10 beauty queens’ legs (5x2=10), and don’t forget your own two legs!
So, that's it! We hope you found the puzzles entertaining!
