Asked by bobblehead to Cathal on 18 Nov 2013.
Question: 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?

He did it using algebra (simultaneous equations); there are 50 people and 24 horses. 🙂

Genius
bobblehead commented on :
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.
