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

   Option E
   Required percentage = (250 – 120)/250 * 100 = 52%
   
    



7. What is the ratio of the number of boys to girls in COMPUTER and ENGLISH department together?
   4:1
   5:1
   2:1
   3:1
   6:1
   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
   
   
    



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

    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
    Difference = 228 – 162 = 66
