What is total number of Cows in the farm?

Question

Some cows and Hens are living in a farm. Total number of eyes in that farm are 172. Total number of Legs are 344. Then, what is total number of Cows in that farm? (Note that, Cows and Hens are there. (1Cow leg=4, 1Hen leg=2), (1Cow eyes=2, 1Hen Eyes=2). Please give an answer.

Answer 1

for the eyes, and C for cow and H for hen

2 C + 2 H = 172

for the legs

4 C + 2 H = 344

subtract the eye expression from the leg expression

2C = 172

C = 86 cows

substitute this into the eyes expression

2(86) + 2 H = 172

H = 0

must be a cattle ranch, there are NO hens

Answer 2

172 eyes divided by 2 is equal to 86 animals

If all 86 are cows then 86 multiply by 4 is 344 legs;

There is no space for hen.!!

Answer 3

He has offered 4/5 of his goats , and 3/5 of his cows. this ability that the form of goats he had initially ought to be a dissimilar of 5. further for the form of cows. If we in simple terms flow interior the process the countless multiples 5 , 10 , 15 , 20 , 25 , 30 , we can see that the only case the place the entire form of goats and cows offered equals 29 , is the place he offered 20 goats out of 25 , and 9 cows out of 15. consequently , he had 5 goats left , and six cows left. The ratio you're in seek of is 5 : 6.

Answer 4

86 Cows and no hens

Answer 5

Hmmm.....

Only 86 cows but there are no hen.

344/4=86

172/2=86

so there are no place for hen ok........

Answer 6

only 86 cows no hens

Answer 7

2C + 2H = 172

C + H = 86

C = 86 - H



4C + 2H = 344

4(86 - H) + 2H = 344

344 - 4H+ 2H = 344

-2H = 0

H = 0

C = 86
