Question

How many cows and hens if they have 50 head and 142 legs?

Answer 1

Answer:

29 hens

and

21 cows

hens =29multiply by 2 = 58legs

cows = 21multiply by4=84legs

84legs + 58 legs=142 legs

Answer 2

Each cow and hen has one head.

That means there are 50 cows and hens in total.

Each cow has 4 legs.

Each hen has 2 legs.

The maximum number of cows is 35 as 35*4= 140.

The maximum number of hens is 71 as 71*2= 142.

If we take any random number such as 29.

If we take 29 hens.

Then, 29*2=58.

Then,142-58= 84.

If, we divide 84/4=21.

And,

29+21=50.
