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?

Question

atlas · Answer

74 heads means there are 74 humans AND horses in total.
We assume the number of humans to be x
so the number of horses becomes (74-x)

atlas · Answer

Now each person has two legs -> so there are 2x legs
each horse has 4 legs -> 4*(74-x)

atlas · Answer

A/c to the person's count-
2x + 4*(74-x) =196
Solve this to find x which is the number of humans
