    Correct Option: D

    Increase in the price of crude oil in the given month with respect to the corresponding previous months:
    In March → (3980 - 3210) x 100 /3210 ≈ 24%
    In April → (4800 - 3980) x 100/3980 = 20.6%
    In May → (4940 - 4800)/4800 x 100 ≈ 3%
    In June → (4970 - 4940)/4970 x 100 = 0.6%
    In July → (5730 - 4970 )x100 /4970 = 15.3%
    In August → (6250 - 5730)x 100/5730 = 9.07%

  1. If in April the crude oil price would have been lesser than the given by Rs. 223 per metric tonne then how much would have been the percentage increase in price over the earlier month?

    In April, crude oil price = Rs. 4800 per metric tonne.
    So, reduced crude oil price = 4800 - 223 = Rs. 4577

    Correct Option: D

    In April, crude oil price = Rs. 4800 per metric tonne.
    So, reduced crude oil price = 4800 - 223 = Rs. 4577
    Hence, required percentage = 4577 - 3980/3980 x 100 = 15%

  1. Based on given graph, Answer the below question.
    Out of a total 550 students, how many students did not prefer Math or Economics?













  1. View Hint View Answer Discuss in Forum

    ∵ Total numbers of students do not prefer Maths or Economics = % of Total numbers of students do not prefer Maths or Economics x Total numbers of students

    Correct Option: D

    From above given graph , we have
    Total numbers of students = 550
    Numbers of students prefer Maths = 12 %
    Numbers of students prefer Economics = 16 %
    Total numbers of students prefer Maths or Economics = 12 + 16 = 28
    Total numbers of students do not prefer Maths or Economics = (100 - 28 )% = 72%
    ∴ Total numbers of students do not prefer Maths or Economics = % of Total numbers of students do not prefer Maths or Economics x Total numbers of students

    ∴ Total numbers of students do not prefer Maths or Economics = 72 x 550 = 396
    100
