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?
is the answer -
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.
is that correct
yes, and it checks. The best way to check these is go back and see if it works in the problem statement.
