Correct Answer: 2006

Solution : Fail percentage in 2006 = $\frac{\text{Failed students in 2006}}{\text{Total students}}×100=\frac{30}{20+60+60+30}×100=\frac{30}{170}×100=17.65\%$
Fail percentage in 2007 = $\frac{\text{Failed students in 2007}}{\text{Total students}}×100=\frac{40}{30+60+60+40}×100=\frac{40}{190}×100=21.05\%$
Fail percentage in 2008 = $\frac{\text{Failed students in 2008}}{\text{Total students}}×100=\frac{60}{50+70+60+60}×100=\frac{60}{240}×100=25\%$
So, as we can see in 2006, a lesser percentage of students have failed.
