Question 1169051
.


        The  " solution "  by @CPhill is out of logic and out of elementary  Arithmetic.


        Here I will give my solution for question  (a).



<pre>
The sample amount is 10,000.


An hour is three times 20 minutes.

 
Production for the first 20 minutes  2*10,000 = 20,000.


Production for the next  20 minutes  2*20,000 = 40,000.


Production for the last  20 minutes  2*40,000 = 80,000.


Total production for one hour is  20,000 + 40,000 + 80,000 = 140,000.    <U>Answer to question (a)</U>
