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

Answers (1)

No. of ducks be y and cows be x
We have no of heads = x+y
                   no of legs = 2y+4x

According to the question

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

          ⇒ x=12
No. of cows were 12.
