Answer: 20 cows
Step-by-step explanation:
Let's denote the number of peacocks as P and the number of cows as C.
Each peacock has one head and two feet.
Each cow has one head and four feet.
We can write two equations based on the information given:
Now, we can solve these equations to solve for C, the number of cows.
From the first equation: P = 60 - C
Substituting this equation into the second equation:
2(60 - C) + 4C = 160
120 - 2C + 4C = 160
120 + 2C = 160
2C = 40
C = 20
