Question

a farmer has some hen and cows. total number of feet is 128 total number of animals are 40. how many hens and cows are there.

Answer 1

sixty cows and 70 aminj

Answer 2

let the no. of hens =x, then no. of cows =40-x
total no. of legs of hens=2x and for cow=4(40-x)
2x+4(40-x)=128(As total no. of legs are 128)
2x+160-4x=128
160-128=2x
x=16
Hence total no. of hens =16 and cows =24
