Answer: The average age is 7.1 years.
This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.
To start, lets multiply the total number of children by their individual ages.
6 x 5 = 30 years
14 x 8 = 112 years
There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of bushels of peanuts = 800
Price of each bushels of peanuts = $5.85
And there is mark up rate = 33%
So, Total price would be

If there is spoilage rate = 21%
So, the remaining rate would be 1-0.21=0.79
so, Number of remaining bushels of peanuts would be

So, Selling price per bushel would be

Hence, Option 'c' is correct.
