Answer 1

The Correct Option is A

\(2006 = \frac{130}{1008} = 12.9\)

\(2007 = \frac{160}{1103} = 14.5\)

\(2008 = \frac{190}{1143} = 16.62\)

\(2009 = \frac{220}{1198} = 18.36\)

\(2010 = \frac{240}{1208} = 19.86\)

\(2011 = \frac{238}{1203} = 19.78\)
So, 2010 is the year for which zone V is maximum.
So the correct option is (A)

Answer 2

Total number of qualifying candidates in 2009 =
\(650 + 560 + 510 + 500 + 220 + 490\)
\(= 2930\)
total number of qualifying candidates in 2011 =
\(648 + 612 + 588 + 580+238+534\)
\(=3192\)
\(\%\) required = \(3192 - \frac{2930}{3192}\)
= \(\frac{262}{3192}\)
= 8.2\(\%\)
So the correct option is (A)

Answer 3

2009:
Appeared
Boys = \(\frac{7}{10} \times 2468 = 1728\)

Girls = \(\frac{3}{10} \times 2468 = 740\)

Qualified
Boys =\(\frac{3}{5} \times 500 = 300\)

Girls = \(\frac{2}{5} \times 500 = 200\)
Ratio required = \(\frac{300}{740}\)
\(= 0.4\)
\(\frac{2}{5}\) approx
So the correct option is (B)

Answer 4

Zone 1: not continuous increase
Zone 2: not continuous increase
Zone 3: not continuous increase
Zone 4: not continuous increase
Zone 5: not continuous increase
Zone 6: not continuous increase
Not in any zones there is continuous increase.
So the correct option is (D)

Answer 5

Number of students appeared from zone V in 2008 and 2011 together =
1143 + 1203
= 2346
Number of students appeared from zone II in 2007 and 2010 together =
2899 + 3608
= 6507
\(\%\) required = \(6507 - \frac{2346}{6507}\)
= 63.55\(\%\)
So the correct option is (A)
