Answer:
let say each animal eat x amount of food per day
→ Amount of food eaten by 28 animal for 1 day
=28×x
→ Amount of food required for 28 animal for 9 days
=28x×9
=(28×9)x 252x
The farmer has 252x amount of food.
now, the number if animal =28+8=36.
No.of days the food will last=food required for 1 dayamount of food
food required for 1 day =(no.of animals)×x
food requires for 1 day =36x
No. o days food will last =36x252x=36252=7
∵The food last for 7 days if 8 animals are added
