A man has some hens and cows. If the number of heads be 48 and the number of feet equals 140, then the number of hens will be:

A.	22	B.	23
C.	24	D.	26

Answer and Explanation

Answer:26

Explanation:
Let the number of hens be x and the number of cows be y.
Then, x + y = 48 .... (i)
and 2x + 4y = 140 x + 2y = 70 .... (ii)
Solving (i) and (ii) we get: x = 26, y = 22.
The required answer = 26.
