# Hens and pigs

Hens and pigs have 46 feet in total. At least how much can heads have?

Result

n =  12

#### Solution:

$46=2s+4p \ \\ p=46/4=\dfrac{ 23 }{ 2 }=11.5 \ \\ \ \\ p_{1}=\lfloor p \rfloor=\lfloor 11.5 \rfloor=11 \ \\ s_{1}=(46 - 4 \cdot \ p_{1})/2=(46 - 4 \cdot \ 11)/2=1 \ \\ \ \\ n=s_{1}+p_{1}=1+11=12$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
