A lot consists of 4 sublots of 500 tons each. If the third sublot sample is drawn at 312 tons, what is the total lot size?

Explanation:
The key idea is that the total lot size comes from adding up all the sublots, not from the amount sampled from one sublot. Here, there are 4 sublots and each is 500 tons. Multiply 4 by 500 to get 2000 tons. The fact that a sample from the third sublot is 312 tons doesn’t change the total mass of the lot; it just tells you how much was taken for testing from that sublot. So the total lot size is 2000 tons.
