    b) 1998
    c) 1999
    d) 2000

    (3) In the year 1997, which state had the lowest percentage of candidates selected over the candidates appeared?
    a) Delhi
    b) H.P
    c) U.P
    d) Punjab

    a) 79.5%
    b) 81%
    c) 84.5%

    (5) The percentage of candidates selected from U.P over those qualified from U.P is highest in the year?
    a) 1997
    b) 1998
    c) 1999
    d) 2001

    Solution

    (1) Option 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 = 72.5
    For Punjab = (85 + 70 + 65 + 84 + 60)/5 = 364/5 = 72.8
    For Haryana = (75 + 75 + 55 + 60 + 75)/5 = 340/5 = 68
    Clearly, this average is maximum for Delhi.

    (2) Option D
    The percentages of candidates qualified from Punjab over those appeared from Punjab during different years are:
    For 1997 680/8200 × 100 = 8.29%
    For 1998 600/6800 × 100 = 8.82%
    For 1999 525/6500 × 100 = 8.08%
    For 2000 720/7800 × 100 = 9.23%
    For 2001 485/5700 × 100 = 8.51 %

    (3) Option D
    The percentages of candidates selected over the candidates appeared in 1997, for various states are:
    For Delhi 94/8000 × 100 = 1.175%
    For H.P 82/7800 ×100 = 1.051%
    For U.P 78/7500 × 100 = 1.040%.
    For Panjab 85/8200 × 100 = 1.037%.
    For Haryana 75/6400 × 100 = 1.172%
    Clearly, this percentage is lowest for Punjab.

    (4) Option D
    Required percentage = [(75 + 75 + 55 + 60 + 75)/(94 + 48 + 82 + 90 + 70)] × 100
    = 340/384×100
    = 88.54%

    (5) Option B
    For 1997 78/720 × 100 = 10.83%
    For 1998 85/620 × 100 = 13.71%
    For 1999 48/400 × 100 = 12%
    For 2000 70/650 × 100 = 10.77%
    For 2001 80/950 × 100 = 8.42%

    DIRECTIONS: Study the following table and answer the questions.

    Solution

    (1) OPTION D
    Required percentage = [(140-108)/108 × 100] = 34.26

    (2) OPTION C
    The total sales (in thousands) of all the seven years for various batteries are:
    For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
    For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
    For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
    For 35AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
    For 55AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.

    (3) OPTION D
    Required difference = [(84 - 45) x 1000] = 39000.

    (4) OPTION D
    The percentages of sales of 4AH batteries to the total sales in different years are:
    For 1992 = 75/543 × 100=13.81%
    For 1993 = 90/528 × 100=17.05%
    For 1994 = 96/525 × 100=18.29%
    For 1995 = 105/510 × 100= 20.59%
    For 1996 = 96/465 × 100=19.35%
    For 1997 = 105/495 × 100=21.21%
    For 1998 = 115/605 × 100=19.01%

    (5) OPTION B
    From the table it is clear that the sales of 7AH batteries have been decreasing continuously from 1992 to 1997.
