Question

In a group of cows and hens, the number of legs are 24 more than the twice of number of heads. What is the number of cows in the group?

Answer 1

Answer:

12

Step-by-step explanation:

Let the number of cows be x and number of hens be y

Number of legs in each:

Hen = 2

Cow = 4

Then, according to question

4x + 2y = 2(x + y) + 24

4x + 2y = 2x + 2y + 24

4x + 2y - 2x - 2y = 24

2x = 24

x = 24/2

x = 12
