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.

Depends whats hard for you.
n+1=n solve for n.
e=mc2=236gh=(mc=gh)x26=zx-12
9999,000,999,000 x 2222222 - 10 + 5 x 200

That's hard to say.
Anyone can if they work hard at it.

This one may be confusing its 1.12933E.2394 + 9.1879E98.234 Yet this is hard
John was smiling all day after answering the hardest math problem of the day.

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.
