Solutions :
Data Interpretation Problem I1.
Qualified female candidates from State P in 2008 = 126
Male : Female = 11 : 7
=> Qualified male candidates =(11/7) x 126 = 198
=> Total qualified candidates = 198 + 126 = 324
=> Number of candidates appeared at the exam = (326/60) x 100 = 540
2.
Let the number of candidates who appeared at the exam in 206 from state Q = x
=> Number of candidates who appeared in 2007 = 2x
Total qualified candidates who appeared in 2007 = 408
=> ((x x 30) / 100) + ((2x x 45) / 100) = 408
=> 30x + 90x = 40800
=> 120x = 40800
=> x =40800/120 = 340
3.
Qualified candidates from state P :
Year 2006 => ((450 x 60) / 100) = 270
Year 2007 => ((600 x 43) / 100) = 258
=> Required difference = 270 - 258 = 12
4.
Total qualified candidates from state Q in 2008, 2009 and 2010 = 3 x 210 = 630
Number of qualified candidates in 2008 and 2009
= ((280 x 60) / 100) + ((550 x 20) / 100) = 168 + 275 = 443
=> Number of qualified candidates in 2010 = 630 - 443 = 187
5.
Number of qualified candidates from state P in 2009 = ((480 x 70) / 100) = 336
Number of qualified candidates in 2010 = ((336/14) x 9) = 216
Data Interpretation Problem II
1.
People who travel by train B on Friday = ((200 x 120) / 100) = 240
=> Required ratio = 240 : 320 = 3 : 4
2.
Required difference
= (350 + 270) - (200 + 170)
= 620 - 370 = 250
3.
Required average
= (240 + 210 + 140 + 230) / 4 = 820 / 4 = 205
4.
Required percentage decrease = ((350 + 210) / 350) x 100
= 14000/350 = 40%
5.
People who travel by both trains :
Sunday => 270 + 310 = 580
Wednesday => 140 + 120 = 260
=> Required percent = ((580-260)/260) x 100
= 32000/260
This is approximately equal to 123
solutions are so well explained. Appreciated!
