In which year is the production the minimum ?


Step 1: Total production each year
2011: \( 300+250+150+200 = 900 \).
2012: \( 350+150+50+250 = 800 \).
2013: \( 300+400+200+100 = 1000 \).
2014: \( 350+100+150+200 = 800 \).
2015: \( 300+150+250+350 = 1050 \).
2016: \( 400+300+350+250 = 1300 \).
Step 2: Find minimum Minimum total = 800 (in 2012 and 2014). \[ \boxed{2012 \text{ and } 2014} \]
