10%
11%
12%
13%
Correct answer is D
Required percentage = [ (82 + 70 + 48 + 65 + 55)/(640 + 560 + 400 + 525 + 350) ] %
= [ 320/2475 x 100 ] %
= 12.93%
≈ 13%

Number of Candidates Who Appeared, Qualified and Selected in a Competitive Examination from Five States Delhi, H.P, U.P, Punjab and Haryana Over the Years 1994 to 1998
The percentage of candidates selected from U.P over those qualified from U.P is highest in the year?
1997
1998
1999
2001
Correct answer is B
The percentages of candidates selected from U.P. over those qualified from U.P. during different years are:
For 1997 = ( 78/720 x 100 ) % = 10.83%
For 1998 = ( 85/620 x 100 ) % = 13.71%
For 1999 = ( 48/400 x 100 ) % = 12%
For 2000 = ( 70/650 x 100 ) % = 10.77%
For 2001 = ( 80/950 x 100 ) % = 8.42%
Clearly, this percentage is highest for the year 1998.

Number of Candidates Who Appeared, Qualified and Selected in a Competitive Examination from Five States Delhi, H.P, U.P, Punjab and Haryana Over the Years 1994 to 1998
For which state is the average number of candidates selected over the years the maximum?
Delhi
H.P
U.P
Punjab
Correct answer is A
The average number of candidates selected over the given period for various states are:
For Delhi = (94 + 48 + 82 + 90 + 70)/5 = 384/5 = 76.8
For H.P. = (82 + 65 + 70 + 86 + 75)/5 = 378/5 = 75.6
For U.P. = (78 + 85 + 48 + 70 + 80)/5 = 361/5 = 72.2
For Punjab = (85 + 70 + 65 + 84 + 60)/5 = 364/5 = 72.8
For Haryana = (75 + 75 + 55 + 60 + 75)/5 = 340/5 = 68

Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.
40-45
30-40
20-30
Below 20
Correct answer is C
Since 66 students get 20 and above marks in Chemistry and out of these 21 students get 30 and above marks, therefore to select top 35 students in Chemistry, the qualifying marks should lie in the range 20-30
Study the following table and answer the questions.
Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.
The number of students scoring less than 40% marks in aggregate is?
13
19
20
27
Correct answer is D
We have 40% of 50 = ( 40/100 x 50 ) = 20
Therefore Required number
= Number of students scoring less than 20 marks in aggreagate
= 100 - Number of students scoring 20 and above marks in aggregate
= 100 - 73
= 27
Study the following table and answer the questions.

21%
27%
29%
31%
Correct answer is C
Number of students getting at least 60% marks in Chemistry
= Number of students getting 30 and above marks in Chemistry
= 21
Number of students getting at least 40% marks in aggregate
= Number of students getting 20 and above marks in aggregate
= 73
Required percentage = ( 21/73 x 100 ) %
= 28.77%
≈ 29%.
