    According to given table, we have
    Total number of students scoring marks less than 50% = 240 + 220 + 300 + 280 + 210 = 1250
    Total number of students scoring marks exactly 50% = 55 + 40 + 20 + 10 + 25 = 100

    Correct Option: C

    According to given table, we have
    Total number of students scoring marks less than 50% = 240 + 220 + 300 + 280 + 210 = 1250
    Total number of students scoring marks exactly 50% = 55 + 40 + 20 + 10 + 25 = 100
    Required ratio = 1250 : 100 = 25 : 4

Direction: The following table gives zone wise survey report of the people of a country who take coffee. Study the table and answer the questions.

  1. The ratio of the total number of people surveyed who take coffee more than 3 times a day to the total number of people who do not take coffee at all is

    As per the given above table , we see
    Number of people who take coffee more than 3 times a day = 410 + 310 + 700 + 1450 = 2870
    Total number of people who do not take coffee at all = 950 + 430 + 620 + 50 = 2050
    Required ratio = Number of people who take coffee more than 3 times a day : Total number of people who do not take coffee at all

    Correct Option: B

    As per the given above table , we see
    Number of people who take coffee more than 3 times a day = 410 + 310 + 700 + 1450 = 2870
    Total number of people who do not take coffee at all = 950 + 430 + 620 + 50 = 2050
    Required ratio = Number of people who take coffee more than 3 times a day : Total number of people who do not take coffee at all
    ∴ Required ratio = 2870 : 2050 = 1.4 : 1 = 14 : 10 = 7 : 5

    On the basis of given table in question ,
    Total people in north zone = 4840
    Total people in south zone = 3390
    Total people in east zone = 2820
    Total population = 4840 + 3390 + 2820 = 11050
    People who take coffee only once a week in these zones = 620 + 540 + 350 = 1510

    Correct Option: D

    On the basis of given table in question ,
    Total people in north zone = 4840
    Total people in south zone = 3390
    Total people in east zone = 2820
    Total population = 4840 + 3390 + 2820 = 11050
    People who take coffee only once a week in these zones = 620 + 540 + 350 = 1510

    Required percent =
    1510
    		× 100 ≈ 14
    11050
