Concept:Average daily weight gain is calculated by dividing the total weight gained by the total number of days in the given period.
Explanation:The beef cow gained a total of
75 kg of body weight.
The time period is given as 2 months and 2 days.
Assuming 1 month has 30 days, 2 months equals
2×30=60 days.
So, the total time period is
60+2=62 days.
Now, divide the total weight gain by the total days to find the average daily gain:
Average weight gain per day
=6275 kg/day.
75÷62=1.2096, which is approximately
1.21 kg/day.
This means the cow gained about 1.21 kg of weight each day on average.
Answer:The average weight gain is
1.21 kg.
Therefore, the correct option is B.
