Question

A man has some hens and cows. if the no of heads be 48 and the no of feet equal to 140 then the no hens will be:-?? ​

Answer 1

Answer:

26

Step-by-step explanation:

Number of heads = 48

Number of feet = 140

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

x + y = 48    ....(1)

2x + 4y = 140

i.e. x + 2y = 70     ....(2)

Subtracting (1) from (2), we get

y = 22

Hence, x = 48 - 22 = 26

Hence, the number of hens is 26.
