Correct Answer: 2008
Explanation:
As per given graph, we can calculate
Number of Matriculate job-seekers :
In 2003 ? 1400 - 650 = 750
In 2004 ? 1625 - 1000 = 625
In 2006 ? 2300 - 1250 = 1050
In 2008 ? 1400 - 2200 = 1800
Hence, in 2008, number of Matriculate job-seekers was maximum.
Correct Answer: 2375
Explanation:
In 2004. total number of job seekers = 1625
In 2008. total number of job seekers = 4000
