Question

54kg of corn would feed 35 horses for 21days in how many days would 72kg of it feed 28horses

Answer 1

35 horses >>>>>>21 days for 54 kg
35 horses>>>>>>>1 day for 54/21 kg
if 35 horses >>>>>> 1 day for 54/21 kg
then,
1 horse >>>>>>>>> 1 day for (54/21)/35 kg
28 horse>>>>>>>> 1 day for (54/21)/35*28 kg
it means, (54/21)/35*28 kg for 28 horses in 1 day
$72 \: k.g. \: for \: 28 \: horses \: in \: \frac{1}{(54/21)/35*28 kg} \: \times 72$




$1k.g. \: for \: 28 \: horses \: in \: \frac{1} { (54/21)/35*28 kg} \: \times \: 72$

$\: \: \: \: \: = 35 \: days$
