The graph above shows wheat production in million metric tons (blue bars) and yield in metric tons per hectare (orange line) for a country from 2000 through 2010.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
The total land under wheat in 2003 was approximately than that in 2002.
The largest percentage drop in yield per hectare was .
Official Solution:
Drop-down 1:
To calculate the land area under wheat, we divide wheat production by yield per hectare. For 2002, this is approximately \(\frac{2.9}{1.5} \approx 1.9\), and for 2003, it is approximately \(\frac{5.8}{2.4} \approx 2.4\). This represents an increase of approximately 25% from 2002 (1.9) to 2003 (2.4).
Drop-down 2:
To determine the largest percentage drop in yield per hectare, look for the steepest decline from left to right on the graph. This occurs between 2005 and 2006.
Correct answer:
Dropdown 1: "25% more"
Dropdown 2: "Between 2005 and 2006"

Bunuel - I got confused by the markings the right hand side's y-axis. They are not equally spaced. This prevented me from extracting numbers in time.
Any thought on such discrepancies and how to look at them?
Also - the approximations you've done(wrt calculations), are you approximating numbers in head using the concepts from NT or using calculator?
Calc will take more time but wouldn't want to go too far in approximations.
Any way I can get better at approximations?
Thanks.
