If you can correctly solve it you win. Good luck! One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there? 24 horses, 50 humans (196-(2x74))/2=24 (#horses) Very good. I shall return later with a harder problem. But my brain already hurts, lol. Happy birthday Calm Chaos!!! Terrible twos? Calm Chaos... are you feeling it yet? ID: 708630 ·

Short of algebra, the explanation might suggest how to handle all such similar problems. Assuming no mutations/injuries (to heads or legs), humans and horses each have one head. Multiplying 74 by 2 will account for both all the human legs and 1/2 the horse legs. Subtracting that from 196 will indicate how many horse legs are left. We've already accounted for 2 of the 4 legs for each horse, so, finally, divide by 2. :) Happy birthday Calm Chaos!!! Terrible twos? Calm Chaos... are you feeling it yet? ID: 708637 ·

There they find lots of coconuts and a monkey. During their first day they gather coconuts and put them all in a community pile. After working all day they decide to sleep and divide them into two equal piles the next morning. That night one castaway wakes up hungry and decides to take his share early. After dividing up the coconuts he finds he is one coconut short of ten equal piles. He also notices the monkey holding one more coconut. So he tries to take the monkey's coconut to have a total evenly divisible by 10. However when he tries to take it the monkey conks him on the head with it and kills him. Later another castaway wakes up hungry and decides to take his share early. On the way to the coconuts he finds the body of the first castaway, which pleases him because he will now be entitled to 1/9 of the total pile. After dividing them up into nine piles he is again one coconut short and tries to take the monkey's coconut. Again, the monkey conks the man on the head and kills him. One by one each of the remaining castaways goes through the same process, until the 10th person to wake up gets the entire pile for himself. What is the smallest number of possible coconuts in the pile, not counting the monkeys? ID: 708657 ·

With 2519 coconuts they were always one short, the monkey never gave up #2520. 2520 is divisable by 9, 8, 7, etc. :) Happy birthday Calm Chaos!!! Terrible twos? Calm Chaos... are you feeling it yet?
