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?
answer:i made this so wathc
Let's assume that HM = Human and
HR = Horse
HM + HR = 74
2HM + 4HR = 196
(2HM + 4HR) - (2 HM + 2HR) = 196 - 148
2HR = 48
HR = 24
HM + (24) = 74
HM = 74 - 24
HM = 50
So, the solution is 24 horses and 50 humans.

What is hard for some people may not be hard for others. So there is really no answer to this question.
Different people find different problems hard and so it is difficult to answer the question.
That's a easy one chickens
There is no "hardest" problem. Something that you might find hard might appear easy to someone else and conversely. Also, some of the harder problems do not have solutions yet - if they had been solved then they could not have been so hard!
