The farmer

The farmer calculated that the supply of fodder for his 20 cows was enough for 60 days. He decided to sell 2 cows and a third of the feed. How long will the feed for the rest of the peasant's herd last?

Result

t =  44.444 d

Solution:


20*60 -20*60/3 = t*(20-2)

54t = 2400

t = 4009 ≈ 44.444444
