    Required percentage = (25 + 120) x 100/536

    Correct Option: A

    Required percentage = (25 + 120) x 100/536 = 100≈ 27

  1. The total number of students who have opted the course of Business Management and the course of Stenography exceeds the number of students studying in typewriting course by:

    ∵ Number of students in Business Management course = 160
    Number of students in typewriting course = 261
    Number of students in stenography course = 215

    Correct Option: A

    ∵ Number of students in Business Management course = 160
    Number of students in typewriting corse = 261
    Number of students in stenography corse = 215
    ∴ Requied percent = (160 + 215 - 261/261) x 100 ≈ 44%

  1. In which of the following courses, percentage of girls is the highest?








  1. View Hint View Answer Discuss in Forum

    Percentage of girls in Business Management course = (25 + 25) x 100/160 = 31.25
    Percentage of girls in typewriting course = (23 + 20) x 100/261 = 16.47
    Percentage of girls in stenography course = (25 + 12) x 100/215 =12.56
    And percentage of girls in typewriting and stenography course = (12 + 3) x 100/120 = 12.50

    Correct Option: B

    Percentage of girls in Business Management course = (25 + 25) x 100/160 = 31.25
    Percentage of girls in typewriting course = (23 + 20) x 100/261 = 16.47
    Percentage of girls in stenography course = (25 + 12) x 100/215 =12.56
    And percentage of girls in typewriting and stenography course = (12 + 3) x 100/120 = 12.50
    Hence, it is clear from the above that percentage of girls in Business Management course is the highest,

Direction: Study the following table carefully and answer the question given below.

    In society A:
    Number of children = 25/100 x (250 + 350) = 1/4 x 600 = 150
    Number of male children = 40/100 x 150 = 60
    Number of female children = 150 - 60 = 90
    Similarly calculate for other society also.

    Correct Option: B

    In society A:
    Number of children = 25/100 x (250 + 350) = 1/4 x 600 = 150
    Number of male children = 40/100 x 150 = 60
    Number of female children = 150 - 60 = 90
    In society B:
    Number of children = 40/100 x (400 + 150) = 2/5 x 550 = 220
    Number of male children = 75/100 x 220 = 165
    Number of female children = 220 - 165 = 55
    In society C:
    Number of children = 16/100 x (300 + 275) = 4/25 x 575 = 92
    Number of male children = 25/100 x 92 = 23
    Number of female children = 92 - 23 = 69
    In society D:
    Number of children = 25/100 x (280 + 300) = 1/4 x 580 = 145
    Number of male children = 80/100 x 145 = 116
    Number of female children = 145 - 116 = 29
    In society E:
    Number of children = 40/100 x (180 + 250) = 2/5 x 430 = 172
    Number of male children = 50/100 x 172 = 86
    Number of female children = 172 - 86 = 86
    In society F :
    Number of children = 24/100 x (325 + 300) = 6/25 x 625 = 150
    Number of male children = 46/100 x 150 = 69
    Number of female children = 150 - 69 = 81
    Hence, total number of female children = 90 + 55 + 69 + 29 + 86 + 81 = 410
    Total Number of adult female = (350 + 150 + 275 + 300 + 250 + 300) - 410
    = 1625 - 410 = 1215
    Hence, required ratio = 1215 : 410 = 283 : 82

  1. What is the respective ratio of the total number of adult males in the societies A and B together to the total number of adult males in the societies E and F together?








  1. View Hint View Answer Discuss in Forum

    Total number of adult males in the society A and B = (250 + 400) - (60 + 165)
    Total number of adult males in the society E and F = (280 + 325) - (86 + 69)

    Correct Option: B

    Total number of adult males in the society A and B= (250 + 400) - (60 + 165) = 650 - 225 = 425
    Total number of adult males in the society E and F = (280 + 325) - (86 + 69) = (180 + 325) - (86 + 69) = 505 - 155 = 350
    Hence, required ratio = 425 : 350 = 17 : 14
