What is the ratio of total imports to the total exports for all the given years together?

Percentage increase in export = (previous year export - current year export) x 100/current year export.
In 2003.
Percentage increase in export = (45 - 40) x 100 /40 = 12.5%
In 2004. there is decrease in export over the previous year.
In 2005.
Percentage increase in export = (40 - 35) x 100/35 = 14.29%
In 2008.
Percentage increase in export = (55 - 50) x 100/ 50 = 10%

The answer will be year 2005 and 14.2. The correct option is (c).

In 2002-03, Total import = 35 + 30 = Rs. 65 crores
Total export = 40 + 55 = Rs. 95 crores
In 2004-05 . Total import = 40 + 50 = Rs. 90 crores
Total export = 35 + 40 = Rs. 75 crores
In 2005-06, Total import = 40 + 50 = Rs. 90 crores
Total export = 40 + 60 = Rs. 100 crores
In 2007-08, Total import = 60 + 45 = Rs. 105 crores
Total export = 50 + 55 = Rs. 105 crores
Hence, in 2007-08 pair of years the total import is equal to total export.

As per given graph, we calculate the difference in two consecutive years import.
In 2003, change in imports = (35 - 30)/35 x 100 = 100/7 = 13⁹/₇% fall
In In 2004, change in imports = (40 - 30)/ 50 x 100 = 1/3 x 100 = 33¹/₃% rise
In 2006, change in imports = (55 - 50)/50 x 100 = 10% rise
In 2007, change in imports = (60 - 55/55) x 100 = 9¹/₁₁% rise
Hence, in 2007 the percentage rise/fall in imports from the previous year is the lowest.

Students enrolled in 2008 in all three districts ( A + B + C ) = 8000 + 6000 + 7000 = 21000
Students enrolled in district B over all the years ( 2005 to 2010 ) = 5000 + 4000 + 7000 + 6000 + 4000 + 7000 = 33000
? Required Difference = Students in district B over all the years ( 2005 to 2010 ) ? Students in 2008 in all 3 districts
? Required Difference = 33000 ? 21000 = 12000

From given graph , we can see that
Since , In 2008 year is the number of students enrolled in all the given 3 districts together the second highest.
Hence required Answer will be 2008 year .

In 2004, 2005 and 2008, total import = 40 + 50 + 45 = Rs. 135 crores
In 2004, 2005 and 2008, total export = 35 + 40 + 55 = Rs. 130 crores
Required percentage = 130/135 x 100 = 96.3%

In 2004. number of Graduate job-seekers = 375
In 2004. number of Senior Secondary job-seekers = 1000 - 375 = 635
In 2005. number of Graduate job-seekers = 525
In 2005. number of -seekers Senior Secondary job-seekers = 1050 - 525 = 525
Hence, in, 2005, number of Graduate job-seekers was the same as that of Senior Secondary job-seekers.

In the year 2005, the number of job- seekers having their qualifications as Matriculation = 1850 - 1050 = 800

In 2004. total number of job seekers = 1625
In 2008. total number of job seekers = 4000
Required difference = 4000 - 1625 = 2375

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.
