    4. 60%
    5. None of the Above
    Answer – 4. 60% 
    Explanation :
    = 320-200 = 120
    = (120/200)*100
    = 60%

  2. What is the difference between the total number of Shirts sold in both the shops together in October, February & March and the total number of Shirts sold in both the shops together in January, November and December?
    1. 1060
    2. 1070
    3. 1020
    4. 1010
    5. 1050
    Answer – 4. 1010

  5. The total number of shirts sold in Shop “B” in September is 20% less than the number of shirts sold in same town in October. The total number of shirts sold in Shop “B” in April is 20% more than the number of shirts sold in same town in March. what is the respective ratio between the number of shirts sold in September and those sold in April in the same shop?
    1. 2:9
    2. 1:5
    3. 4:9
    4. 2:7
    5. 8:5
    Answer – 5. 8:5
    Explanation :
    Shirts sold in Shop B in September
    = 20% of 120 = 24 = 120-24 = 96
    Shirts sold in Shop B in April
    = 20% of 50 = 10 = 50 + 10 = 60
    Ratio = 96 : 60 = 8:5

II. Study the following information carefully and answer the questions that follow:
Percentagewise distribution of teachers who teach six different subjects
Total Number of Teachers = 1800

      1. If two-ninth of the teachers who teach Physics are females, then the number of male Physics teachers is approximately what percent of the total number of teachers who teach Geography?
        1. 57%
        2. 42%
        3. 63%
        4. 69%
        5. None of these
        Answer – 1. 57%
        Explanation :
        Number of teachers in Physics = 17/100 * 1800 = 306
        Number of male teachers in Physics = 7/9 * 306 = 238
        Number of teachers in Geography = 23/100 * 1800 = 414
        % = 238 / 414 * 100 = 57%

      2. In History, number of male teachers and female teachers are in the ratio of 1:1. If one-third of the teachers who teach Geography are females and the percentage of female teachers in History equals to the percentage of female teachers in Biology then what is the total number of male teachers who teach Geography, History and Biology?
        1. 624
        2. 627
        3. 776
        4. 798
        5. None of these
        Answer – 2. 627
        Explanation :
        Number of male teachers who teach Geography = 2/3 * 23/100 * 1800 = 276
        Number of male teachers who teach History = 1/2 * 27/100 * 1800 = 243
        % of female teachers who teach Biology = % of female teachers who teach Biology i.e 50%
        Therefore Number of male teachers who teach Biology = 50/100 * 12/100 * 1800 = 108
        Total = 276 + 243 + 108 = 627

      3. What is the difference between the total number of teachers who teach History and Physics together and total number of teachers who teach Chemistry and Biology together?.
        1. 352
        2. 362
        3. 342
        4. 353
        5. None of these
        Answer – 3. 342
        Explanation :
        Total number of teacher who teach History and Physics = 44% of 1800
        Total number of teacher who teach Chemistry and Biology = 25% of 1800
        Difference = 19% of 1800 = 342

      4. If one – third of the teachers who teach Chemistry are females and the percentage of male teachers in Maths is 50%. What is the ratio of the male teachers who teach Chemistry to the number of female teachers who teach Maths?
        1. 13 : 7
        2. 7 : 13
        3. 7 : 26
        4. 13 : 6
        5. None of these
        Answer – 4. 13 : 6
        Explanation :
        Number of male teachers who teach Chemistry = 2/3 * 13/100 * 1800 =156
        Number of female teachers who teach Biotechnology = 1/2 * 8/100 * 1800 =72
        Ratio = 156 : 72 = 13 : 6

      5. If the percentage of Chemistry teachers is increased by 50% and percentage of Maths teachers is decreased by 25%, what will be the total number of Chemistry and Maths teachers together?
        1. 390
        2. 379
        3. 469
        4. 480
        5. 459
        Answer – 5. 459
        Explanation :
        Total number of teacher who teach Chemistry = 234 + 117 = 351
        Total number of teacher who teach Maths = 3/4 * 8% of 1800 = 108
        Total number of Chemistry and Maths teachers together = 351 + 108 = 459
