Step-by-step explanation:

Answer 2

Answer - 15 cows.

$\textbf{Explaination}$

=>Consider the food eaten by cow as X

=> So, the PROPORTION :

=> 8 : 6 : : 20 : X

Mean terms = 6 and 20

Extreme TERMS = 8 and X

=> Mean × Mean terms = Extreme × Extreme terms

=>$\mathbf{6×20=8×X}$

=> $\mathbf{120 = 8X }$

=> $\mathbf{8 X = 120 }$

=> $\mathbf{X = 120 / 8 }$

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{ X = 15 }}}}}}}$

So, 15 cows can eat food given to 20 horses .
