A goat consumes 2kg of grass per day and a cow consumes 4kg od grass per day. Two pais of goats and one pair of cattle are released in a santuary with a total biomass of 16000 kg of grass at the time of release. The growth rate of grass accounts for an increase of 1000 kg every 100 days.How grass stands after 100 days

Answer 1

Answer:

13400 kg

Step-by-step explanation:

Find the consumption of grass in a day:

Goat = 2 kg

2 pairs of Goat = 2 x 4 = 8 kg

Cow = 4kg

1 pair of cattle = 4 x 2 = 8 kg

Total consumption = 8 + 8 = 16kg

Find the consumption of grass in 100 days:

1 day = 16 kg

100 days = 16 x 100 = 1600 kg

Find the amount of grass after 100 days:

Amount left = 16000 + 1000 - 1600 = 13400 kg

Answer:  13400 kg

Answer 2

Answer:

1000 kg grass in 100 days

Then, at 1000th day it must be 10,000 kg.
