The number of candidates who qualified the test from Zone R in the year 2010 was approximately what percentage of the number of candidates who appeared from Zone Q in the year 2008?

As per given graph , It is clear that Difference between the appeared candidates and qualified candidates in the zone S :
Hence required answer will be 2007 year , which is second lowest ( 270 ).

Number of candidates qualified in the years 2009 and 2010 together:
Zone = ( Number of candidates qualified in the year 2009 + Number of candidates qualified in the year 2010 ) × 100
Zone S: (11.4 + 5.2) × 100 = 16.6 × 100 = 1660
Zone T:: (6.9 + 9.4) × 100 = 16.3 × 100 = 1630
Hence , Zone T will be the second highest in the years 2009 and 2010 .

According to question,
The population of females above poverty line in State E = 19800
As per given graph,
Proportion of Male and Female above poverty line in State E = 3 : 2
If 2 Female above poverty line then total population above poverty line will be 5 in State E
If 1 Female above poverty line then total population above poverty line will be 5/2 in State E
If 19800 Female above poverty line then total population above poverty line will be 5 x 19800/ 2 in State E
Population of State E above poverty line = 5 x 19800/ 2 = 5 x 9900 = 49500
Percentage population below poverty line in State E = 10 % ( As given in table chart )
? Percentage population above poverty line in State E = ( 100 - 10 ) % = 90 %
? Total population of State E = 49500 x 100 / 90 = 4950 x 100 / 9 = 550 x 100 = 55000
Percentage of population below poverty line in State E = 10 %
Population below poverty line in State E = 55000 x 10 % = 55000 x 10 / 100 = 5500
Ratio of population of males and females below poverty line in State E = 6 : 5
Since population below poverty line is 11 then male population below poverty line = 6
Since population below poverty line is 1 then male population below poverty line = 6 / 11
Hence population below poverty line is 5500 then male population below poverty line = 6 x 5500 / 11 = 6 x 500 = 3000

From above table , we have
Total number of Executives recruited by organisation U in the years 2007 and 2009 = 534 + 510 = 1044
Total number of Executives recruited by organisation P in the years 2007 and 2009 = 506 + 492 = 998
Required ratio = total number of Executives recruited by organisation U in the years 2007 and 2009 : the total number of Executives recruited by organisation P in the same years
Required ratio = 1044 : 998 = 522 : 499

From above table ,
Number of executives recruited by all given organisations
In year 2006 , P = 480 , Q = 495 , R = 464 , S = 508 , T = 488 , U = 518
In year 2006 , Total number of executives recruited by all the organisations = Sum of the number of executives recruited by all given organisations
= 480 + 495 + 464 + 508 + 488 + 518 = 2953
Hence total executives recruited were 2953.
