Hardest Riddle Ever
Some riddles are very challenging not only for children but for adults as well. Below, you will find a great collection of such kind of the hardest riddle ever. You will beg for help for sure!
Question: A fast food restaurant sells chicken in orders of 6, 9, and 20. What is the largest number of pieces of chicken you cannot order from this restaurant?
Answer: 43. After 6 all numbers divisible by 3 can be ordered (because they can all be expressed as a sum of 6’s and 9’s). After 26, all numbers divisible by three when subtracted by 20 can be obtained. After 46, all numbers divisible by three when subtracted by 40 can be obtained. After 46, all numbers fit into one of these 3 categories, so all numbers can be obtained. 43 is the last number that doesn’t fall into one of these categories (44 = 20 + 6 * 4, 45 = 6 * 6 + 9).

John has some chickens that have been laying him plenty of eggs. He wants to give away his eggs to several of his friends, but he wants to give them all the same number of eggs. He figures out that he needs to give 7 of his friends eggs for them to get the same amount, otherwise there is 1 extra egg left. What is the least number of eggs he needs for this to be true?
Answer: 301 eggs. The number of eggs must be one more than a number that is divisible by 2, 3, 4, 5, and 6 since each of these numbers leave a remainder of 1. For this to be true one less than the number must be divisible by 5, 4, and 3 (6 is 2*3 and 2 is a factor of 4 so they will automatically be a factor). 5 * 4 * 3 = 60. Then you just must find a multiple of 60 such that 60 * n + 1 is divisible by 7. 61 / 7, 121 / 7, 181 / 7, 241 / 7 all leave remainders but 301 / 7 doesn’t.
