    Poisonous apples

    OP forgot to state that eating 2 poison apples results in death, while eating only 1 will not cause harm. Therefore Taciav has the correct solution.

    what is your strategy?

    A game token costs $10 to play. The pay out is $100. You can purchase multiple entries if you desire. For each entry you purchase, you must pick the lowest positive number that no one else picks. If there are ten people, including yourself, seeking to purchase tokens, what is your strategy?

    Mouse & Cheese Cube

    The answer should be 25. My "proof" is a brute force programming solution. I have a psuedocode c++ bruteforce solution. I can give the full version if requested. It takes a few seconds to brute force all possible paths. This might count as a proof, depending on if you trust the computer to be reliable. Basically what it does is it generates all possible paths, and then prunes as it goes along so the program dosen't take basically forever, or 6^27 moves. Now a proof will involve some theorems in graph theory, which I don't yet know all that well. Assume the XYZ plane void recursive_dumb_solution( A 3D cube,Position of X, Y, and Z of current spot,direction it went twice ago, direction it went to get here){ if traveled along a direction twice in a row, return to the above function. else if( x<0 || x > 2 || y < 0 || y > 2 || z < 0 || z > 2) AKA if it exited the cube, return. else if(cube[x][y][z] == 1) AKA if visited spot already visited, then return. else{ //mark the current position of the cube as visited. cube[x][y][z] = 1; /////Moves in every direction possible. recursive_dumb_solution(cube, x+1, y, z, length+1,'x',prev_dir); recursive_dumb_solution(cube, x-1, y, z, length+1,'x',prev_dir); recursive_dumb_solution(cube, x, y+1, z, length+1,'y',prev_dir); recursive_dumb_solution(cube, x, y-1, z, length+1,'y',prev_dir); recursive_dumb_solution(cube, x, y, z+1, length+1,'z',prev_dir); recursive_dumb_solution(cube, x, y, z-1, length+1,'z',prev_dir); cube[x][y][z] = 0; return; } }
  11. In this website: rechallenge.xyz there is a riddle crypted somewhere in the page. the riddle seems to be lord of the rings based; the Two Towers to be exact... The main riddle is the infamous quote from Gandalf " The Grey Pilgrim, that's what they used to call me. Three hundred lives of men I've walked this earth and now I have no time. With luck, my search will not be in vain. Look to my coming at first light on the fifth day. At dawn, look to the East." I need your help to find any sub riddles in that quote or somewhere else in the website!

    A little help needed IF you can

    The first 2 digits are the product of the first 2 numbers in the sum: 3*5=15. Then you multiply the first and last numbers: 3*7=21. Finally you add 15+21 and subtract the centre number: 15+21=36, 36-5=31. So if A+B+C=123040, then AB=12, AC=30, and B=42-40=2, so A=6, C=5. In the second version, instead of subtracting the 2nd number, you're adding the first: 3*7=21, 3*8=24, 21+24+3=48. So if D+E+F=303570, DE=30, DF=35, and 65+D=70, making D=5, E=6, F=7.

    A little help needed IF you can

    Hi Geodood, logic is : 3+5+7 = 152131 solved as (3*5) (3*7) (15+21-5) In shorts we can say abc = (a*b)(a*C)(a*b+a*c-b) Then A+B+C = 123040 In this A = 6 B=2 C=5 Similarly for IF 9 + 4 + 5 = 364590 2 + 6 + 8 = 121630 3 + 7 + 8 = 212448 here A+B+C = (A*B) (A*C) (A*B+A*C+A) so THEN D + E + F = 303570 D = 5 E = 6 F = 7

  24. Hi everyone! Today I came across with this riddle that seems simple, but I haven't got a clue on how to solve. IF 3+5+7 = 152131 4+8+6 = 322448 6+2+9 = 125464 THEN A + B + C = 123040 -------------------------- IF 9 + 4 + 5 = 364590 2 + 6 + 8 = 121630 3 + 7 + 8 = 212448 THEN D + E + F = 303570 Thanks in advance

    Poisonous apples

    Probabilities of something occuring in sequence multiply together, they don't add. We could calculate the probability where we don't eat 2 poisonous or where we do. I chose to calculate where we do. For the first bowl. We only care if you eat 2 poisonous apples. The probability the first apple eaten is poisonous is 3/5. Assuming you ate a poisonous apple because that is the only scenario we care about, the probability the second apple is poisonous is 2/4. This is the only scenario eating from this bowl that we die. Multiply this together (3/5 * 2/4) and the chance of dying is 30%. 70% chance you survive. For the second bowl, we do the same thing, but there are multiple possibility branches for this one. The probability the first apple eaten is poisonous is 2/5. The probability the second apple is poisonous is 1/4 if you already ate a poisonous one. So a 10% chance you die after eating the second apple (assuming it is fast poison). If you are still alive then the 2nd apple was not poisonous so that had a probability of 3/4. That makes he probability for the third equal to 1/3. So 2/5 * 3/4 * 1/3 is 10% chance of dying. The chance the first apple is not poisonous is 3/5. So for the second the chance is 2/4, leaving the last at 1/3. So multiply these out and you get 10%%. Due to having 3 scenarios that result in death we have to add those probabilities. 10% + 10% + 10% = 30%. 70% chance we survive. So both bowls have the same odds. Others arrived at this answer, but with the wrong math. Cheers.

    Square in a circle

    From my reading of the problem, the question can be re-phrased: What is the ratio of the sagitta to the radius of a circle where the apothem is equal to the square-root of half the radius squared?
