Difficulty: 2 of 5 Bonus: Cows, horses and dogs (in Just Math) Rating: 4.00
I have cows, horses and dogs, a different prime number of each. If I multiply the number of cows (c) by the total of cows and horses (c+h), the product is 120 more than the number of dogs (d), that is: c*(c+h) = 120 + d.

How many of each do I have?
