Question

While visiting a friend's home, I saw kittens and chickens playing in the backyard. Counting heads, I got 18. Counting feet, I got 50. How many kittens and how many chickens were in the backyard?

Answer 1

11

Explanation:

The 25 pairs of feet were 7 more than the number of heads, so there were 7 kittens. Hence there were 18-7 = 11 chickens.
