1. Study the given table carefully and answer the question that follow:
Number of candidates appeared and qualified for a test (in hundreds) in 6 different years from 5 different zones.
Here App. means Appeared and Qual. Means qualified.
In which years was in zones the different between the appeared candidates and qualified candidates the second lowest?
2005 → (4.2 - 2.4) = 1.8
2006 → (7.4 - 3.3) = 4.1
2007 → (8.3 - 5.6) = 2.7
2008 → (9.3 - 6.4) = 2.9
2009 → (11.4 - 5.2) = 6.2
2010 → (14.2 - 11.4) = 2.8
If was lowest in 2005 and second lowest in 2007

In which years was in zones the different between the appeared candidates and qualified candidates the second lowest?
Solution:
In zone S, the difference between the appeared candidates and the qualified candidates in various years is given below:2005 → (4.2 - 2.4) = 1.8
2006 → (7.4 - 3.3) = 4.1
2007 → (8.3 - 5.6) = 2.7
2008 → (9.3 - 6.4) = 2.9
2009 → (11.4 - 5.2) = 6.2
2010 → (14.2 - 11.4) = 2.8
If was lowest in 2005 and second lowest in 2007
