Quantitative Aptitude: Data Interpretation Questions Set 142

The pie chart given below shows the distribution of the number of men in percentage or in absolute value or in degree in six different cities in china affected by corona. 42.857% of the number of women in city U is 300.

  1. Find the total number of affected person in city S
    200
    220
    210
    190
    205
    Option B
    Percentage of mens in city P = 20%
    Percentage of mens in city Q = 90˚ * 100/360 = 25%
    Percentage of mens in city R = 36˚ * 100/360 = 10%
    Percentage of mens in city S = 5%
    Percentage of mens in city T = 54˚ * 100/360 = 15%
    Percentage of mens in city U = 100% – (20% + 25% + 10% + 5% + 15%)
    = 100% – 75% = 25%
    Number of women affected in city U = 300/42.857 * 100
    = 300 * 7/3 = 700
    Number of men affected in city U = 700 *(100/140) = 500
    Total number of men affected in all the cities together = 500 * (100/25)
    = 2000
    Total number of persons in city S = 100 + 120 = 220

     

  2. If x number of women affected in city Q in the month jan and the number of women affected in city Q in the month jan is 40% of the number of persons in city U in the month Dec. What is the value of x?
    80
    85
    90
    95
    100
    Option A
    Number of women affected in city Q in the year 2018
    = 1200 * 2/5 = 480
    Number of women affected in city Q in the month Jan = 480 – 400 = 80

     

  3. What is the ratio of the total men affected in city R and T together to the difference between the women affected in city U and P?
    5:2
    3:4
    1:5
    6:5
    11:3
    Option A
    Required ratio = (200 + 300): (700 – 500)
    = 500: 200 = 5: 2

     

  4. Number of women affected in city S is what percentage of the average number of men affected in city Q, R and U together?
    10
    20
    30
    40
    50
    Option C
    Required percentage = 120/[(500 + 200 + 500)/3] * 100
    = 120/400 * 100 = 30%

     

  5. If the ratio of the number of persons eats Veg to Non-veg in city T is 2: 1 and the number of women in city T eat Veg is 33.33% more than the number of women in city S. What is the ratio of the number of women to men eat Non – veg?
    1:3
    4:5
    3:7
    5:8
    5: 4
    Option E
    Total persons in city T = 300 + 240 = 540
    Number of persons like Veg = 540 * 2/3 = 360
    Number of persons like Non – veg = 540 * 1/3 = 180
    Number of women persons like veg = 120 * (100 + 33.33)/100
    = 120 * (4/3) = 160
    Number of women persons like Non – veg = 240 – 160 = 80
    Number of men persons like Non – veg = 180 – 80 = 100
    Required ratio = 100: 80 = 5: 4

     

  6. Study the following information carefully and answer the questions given below?

  7. The number of girls in chemistry department is approximately what percent of the total number of students in that department?
    23
    45
    54
    67
    52
    Option E

    Option C
    Number of girls in COMPUTER = 400 – 280 = 120

    Girls in ENGLISH = 500 – 320 = 180
    Girls in BIOLOGY = 350 – 200 = 150
    Girls in Maths = 450 – 220 = 230
    Girls in Chemistry = 250 – 120 = 130
    Required Average = (120 + 180 + 150 + 230 + 130)/5
    = 162

     

  10. What is the difference between the number of boys and girls in BIOLOGY department?
    50

    Girls in BIOLOGY = 350 – 200 = 150
    Girls in Maths = 450 – 220 = 230
    Girls in Chemistry = 250 – 120 = 130
    Average of girls = (120 + 180 + 150 + 230 + 130)/5
    = 162
    Average of boys = (280 + 320 + 200 + 220 + 120)/5 = 228
